Most mods on this list require the Spore ModAPI Launcher Kit in order to work. I strongly recommend you install this before installing any mods.
Editor mods
♦︎Dark Injection created by Davo, now developed by rob55rod - This is imo the nr 1 mod to absolutely have for your spore game. It adds tons of content from darkspore such as creature parts and creature armor, edits spores UI to look more like darkspore, gives you tool parts like invisible limbs and individual ability parts, disables the complexity meter and so much more! And it even comes with force save bundled. It has a handy installer too, so you can easily choose what you want to add in your game and what you want to leave out.
♦︎Enhanced Color Picker by Emd4600 - Another color mod, but this one gives you thousands more colors for your creatures skinpaints then what spore currently has to offer, and gives you more spesific control over what you need.
♦︎B&V Fusion by Mx3brainpower - A mod that adds vehicle parts to the building editor, and visa versa. Not only does it allow you to have complete creative freedom over the building and vehicle editors such as allowing you to place entertainment parts on a factory, but it also adds 144 hidden textures from Spore in all vehicles, buildings and spaceships editors. Extremly good mod for complete creative control with all non-creative editors.
♦︎Spore stacker by Mx3brainpower - Allows MANY creature parts, mainly detail parts, to be stacked. This includes modded parts too. No more fiddling around with limited part placements, now you can finally place those 5 eyes on top of eachother.
♦︎Building rotation mod by DVDmaster - The building rotation mod makes it so you can rotate base and roof parts in building editor, and works very well with B&V fusion.
♦︎Infinite scaling mod by Zarklord - This i think is absolutely essential in complete creative freedom. This mod gives you the ability to enlarge or shrink any part in any editor and allows you to really get into detail without being held back. Note that things that are too big could cause visual glitches.
♦︎New editor backgrounds by THEdragon - A really great mod that adds more custom backgrounds to the editor test drive. Includes good variety like an underwater background and a basic room.
♦︎Hut editor by Vanillacold - Replaces the early creature editor with a tribal hut editor. To use it, go into the early creature creator via the Create menu. (It doesn't replace the in-game one.) Really cool to see a working hut editor!
♦︎Project Bacterioid by IHaveNoIdea. - A mod that unlocks the cell editors true potential. Makes the cell editor 3D, adds creatureparts and limbs, adds rotation and morph handles, and more. A good mod for making much more complex cells to have fun with.
♦︎Advanced CE by VanillaCold - With this mod you have the free XYZ part movement option from the building editor right there in the creature editor. You can really go nuts with this one.
Part mods
♠︎CamBen color pack by CamBen. - Adds plenty of parts in different colors and shades to your editor, making you able to have much more control over what colors your creature is. This gives you more creative freedom and makes you able to finally make that big rainbow cat you always wanted to make.
♠︎Adventureprops by CamBen. - One of my favorites, this one adds plenty of props to the adventure editor. You can create so much more stuff with what you get from here, more gates, citywalls, space props, sattelites, more effects and so on. Really recommend this one!
♠︎Himeric Engine by Clicker95 - a really cool parts mod that add high quality and realistic alien parts, allowing for some pretty unique creations. The textures are a bit weird but they work just fine. THE LINK IS NOT DEAD!! just scroll further in the thread, a reupload has been posted.

This handy mod gives you 4 different fur creature parts so you can finally add some real fuzzy charm to your creations. Comes in 4 types of Thickness and different levels of color, so you can really get more creative opportunities.
♠︎Strange and Beautiful by peridot, reuploaded by Darhagonable - A mod that adds tons of high quality parts, with differnt animations such as a tounge sticking out, when a mouth opens, or bunny-like ears that bends along with your creature. Although it suffers from a few visual bugs, i really recommend this one.
♠︎Drone parts by Deoxys_0 - Do you want to make your robot creature even more robotic, but would rather build it with simpler shapes? Or have complete control over building better armor and robots? Then this is the mod for you! it adds plenty of pages full of robotic parts from machine gun nozzles to simple cubes, all in different coat layer coloring. A high quality mod for making high quality robots...or drones!

♠︎Locked 'N' Loaded by IHaveNoIdea. - A good one for all the edgelords out there. Adds 20 firearms to the editor, from pistols to miniguns. Each weapon is also customisable, as it's colour scheme matches to that of the Creature's skinpaints.
♠︎Unshackled by IHaveNoIdea. - The ultimate tool for creative freedom, breaking free from spores limitations. You can create custom wings, limbs, heads and more with this handy tool. Read OP carefully.

Misc
♣︎Citywalls by Frogottenspore, redone by Darhagonable - A mod that allows you to change the walls to your space and civ cities. I personally love this one because you can use it to get grox walls or a "ruined city" look. Includes 3 custom walls created from scratch that mimics the beta walls from the 2007 beta version of spore.
♣︎InfiniteSOL by ??? - a mod i think its almost necessary..because once you get the staff of life, you basically get a reward for winning the game....but..you can only use it 42 times, which i think is BULLSHIT! so..yeah, use this if you want your PROPER reward. It removes the limit and makes the staff infinite uses.
♣︎Grox archetype by D3vilSheep - so many has dreamed about playing as the grox, and with this one you KINDA can. It replaces the knight archetype in space stage with a "grox one" aka replaces your aliens voice, background and lighting effect with the grox ones. Mix this with the citywall mod to give yourself the grox citywalls and your almost a complete grox. This works in CIV stage as well.
♣︎Empire voice replacement by Kisutora - Are you tired of hearing your alien 56-mouthed lava sheep empire having the voice of a normal human from the sims? Well no longer shall you suffer, for this mod replaces the voice of your empire with any other archetype voice of your choosing. This DOES include the grox voice as well, but if you want the complete grox package with bg and lighting included, i suggest you take a look at the grox arcetype one above.
♣︎Corporations mod by Logarithm64 - Adds several corporations in space stage. Each corporation has unique and special tools that can be obtained from it. In order to obtain these tools, you have to place structures that belong to these corporations on planets. Doing so will gain the corporation "Fame," which is required to unlock these tools. Once they are unlocked, you can purchase them from the from empires that carry them. Good mod for spicing up space stage a bit.
♣︎New plazas by THEdragon - This mod adds more ground textures, aka plazas to the adventure editor. Gives you more varied plazas and decoration to your adventures, as well as different borderless colony textures, great for making your own custom colony!
♣︎Interstellar industries by Ravnodaus - A nice way to freshen up space stage a bit and add a proper challenge. This mod removes spice and adds 40 different kinds of trade goods to find, from fertilizer to titanium, and much more! Some of them are rare to find, so you will need to dust off those binoculars.
♣︎Change home planet by Emd4600 - A truly remarkable mod that allows you to change your home planet in space stage. Enter to one of your planets and execute the cheat: setHomePlanet The planet will now become your home planet. The planet in the galaxy game selector menu remains the same.

♣︎Sneky effects by Snek - Gives you a whopping 300+ new effects in the adventure editor for you to play around with. Most of these are from the game itself, so you can truly get creative like this.
♣︎Sneky graphics by Snek - This one is good for those like me who are sick of spores low LOD. Its perfect for those who wants to take pictures and screenshots in adventures without having to worry about moving close enough. It also keeps texture levels high by default. This mod MIGHT impact preformance.
♣︎Global tester by Snek - Are you tired of your creature doing the same 4 animatios over and over? Are adventures just too bland for you now? Well look no further. This is a technical mod that allows you to play every sound and animation found in the game via the cheat console. Instructions found in the link.
♣︎GA space stage timeline timeline fix by Liskomato - You know that annoying glitch in the games timeline, where the entire thing scrambles up into an unreadable mess when you reach space stage? Well this mod fixes that..but the price to pay is that your creature stage timeline messes up instead. There are ways to prevent this tho. Read the OP carefully.
♣︎Adventure Editor Slot Page Expander by Liskomato - A really revolutionary mod that doubles the amount of page slots in the adventure editor, allowing you to add many more assets into your adventures.
♣︎Colony seaports by ProfAlba - Grants you the much needed options of having colonies with seaports in space stage. Place a colony near water for it to generate one.
Game Tweaks
♥︎The 60 fps fix - The 60 patch just removes the 30 fps cap and makes the game play silky smooth. You can add an even higher number if you so desire.
♥︎Ultimate Graphics Fix. - The ultimate graphics fix makes your creatures skinpaints appear in higher resolution, aka makes your metallic or shiny creatures actually shiny or metallic. It also fixes cell transparency. I wouldn't recommend going above 2048 unless you want tons of crashes.
♥︎Remove the EA/Maxis Intro when starting SPORE - If you are an impatient heck like me, you will like this one. Does what it says; it skips the opening cutscene when starting spore, thus making you start right there at the galaxy screen. Saves you time as well as sadness over maxis' death.
♥︎Spore graphical improvements - A guide on how to improve spores graphics. Pretty much explains itself.
Tools
★Darkspore Creature Converter - This tool is great for ex-darkspore players who wants to save their lost heroes. This will convert your darkspore png to a functioning png that you can load into spore. Dark injection is required for this mod to work.
★SporeModderFX By Emd4600 - The must-have tool for creating spore mods and the package files itself.
★Spore ModAPI Launcher Kit By Emd4600 - Spore ModAPI Launcher Kit contains an easy installer to help you install mods correctly, an uninstaller and a game launcher. Some mods require this in order to be installed correctly, and ALL .sporemod files require this to work. Very good if you arent sure where to install your mods.
★Sporemodder blender-addons By Emd4600 - An addon for the 3D modelling program Blender, which enables you to create and export animated parts and use them in spore, allows you to import .RW4, .GMSH and GMDL files into blender, and more.
