I just downloaded the nude game "Queens of Fighting". Havn't even unzipped it yet, figure it might come in handy for sprite work though.
As for my organization, I've decided to filter and organize my chars by game. Much easier to do it this way and also easier to see which chars I still need.
Mainly, it's going to help me get rid of crap chars (chibi, etc.) that I may have.
After I'm done, I will be posting a NEEDS list of the chars I need for each game.
