Recently I found a game for the Sega Genesis at a local used game store called "Wacky Worlds Creativity Studio". I thought that it was going to be like, the Sega counterpart to Mario Paint, since it had Sonic and Tails on the front of the cartridge (Sonic is only present on the main menu as the cursor), but it turned out to be much less than what I expected.
Basically, none of the menus have any words on them and you can go to one of the many "worlds", move around the objects, and paint some of them different colors. That's pretty much it. So far I have yet to find anything in this game that allows you to draw your own sprites or compose your own music (there is a pattern sequencer, but there aren't very many patterns to choose from).
From the looks of it, this game was most likely made for little kids that weren't old enough to play Mortal Kombat at the time. Also, on the front of the cartridge, it says in multicolored build-a-bear font "Sega Club". I have no idea what this Sega Club might have been, but perhaps it's best not to talk about it.
Likely I'll be keeping this mysterious piece of video game history in my collection, but I probably won't be playing it very often. I have yet to explore more than two worlds and the asteroid containing the credits sequence, so likely I may have missed a lot of other content besides the object painter and the pattern sequencer. For now, though, I'd like to say that I officially don't really like this game all that much, due to its lack of content and fine-grain customization.
Then again, I'm probably just being overly-critical as a narrow-minded fool who spent most of their gaming life on Nintendo consoles.
