What the title of the topic says. Just did a quick search to see there's a topic with the keyword "Spore": nothing of interest. Just found a video from YouTube user named Lighting Flame (channel name: UCV2hwYHwMPyeX5VTyv3X63A) who posted this video on 2014 May 20.
What is particular about the game Spore is that there is an unused stage editor which can be accessed with a mod. Mind that I have no idea how much capable the stage editor is because I never interacted with it; still worth sharing though!
