For consoles - Sonic the Hedgehog, for Sega Genesis. Though before that I had a few computer games. My absolute FIRST game, I don't really remember what it was called, but I always called it "Freddy and the Chickens." It was on a 3 1/2" floppy, and you were Freddy (who looked kinda like Woodstock from Peanuts) and you had to rescue the chickens from a bunch of 8bit green monsters. Ah, nostalgia...I wish still had it...or a system that still had a floppy disc drive, haha.
