SF2 with Dhalsim and Zangief, Bayou Billy on NES, Astrosmash on Atari 2600, Ecco the Dolphin on Sega Genesis, Legacy of the Wizard on NES, Berzerk, Defender, Joust, Burgertime
oh, and Strawberry Shortcake Musical Matchup.
I'm most proud of Bayou Billy, because most people f*ck around on that game like a bunch of hillbillies.
