My most recent purchase was about a month ago when I finally bought a CIB of Comix Zone. So far the game lists for my Genesis Collection is coming to a close. The only games I'm trying to get my hands on still is Ghostbusters, Contra: Hard Corps, and Kid Chameleon. I had a copy of Kid Chameleon months ago but appartently the game didn't work.
Just now, I purchased Spider-Man, the 1994 animated series game based off the televison series. I'm still working on trying to beat Castlevania: Bloodlines but that's still a hard task to do.
