I love tons of bad games. Grand Theft Auto for the Game Boy Color stands out. That's right, gangstas--there was a port of the original GTA to the GBC, and, man, was it shit. Weird bugs let you drive over pieces of water, caused you to disappear from the map and mysteriously die, and never find a pedestrian unless you were in a car. The statistics gave a bank job category, but there was no way to pull a bank job, and even though some missions required you to know what type of vehicle you were in (and the manual said the game could tell you), no vehicle name ever popped up onscreen. Even so, the game let you jack a car and run people over, shooting things along the way, and gave a nice variety of missions, a surprising array of vehicles, and three cities to screw around in. It was crap, but it was fun crap.
Oh, and Yoda Stories for the GBC. Yes, I know, it was a tile-based, weak sauce version of Zelda with fifteen levels that weren't connected (and that you couldn't save inside). That's all it was supposed to be. It was on the Game Boy Color, for Jeebus's sake. It had the processing power of my watch. Cut it some slack.
Oh--one last thing. The original Super Mario Land for Game Boy, all forty-five minutes of it, was the shit. That is all.
Wait, not all. Elite Beat Agents for the DS is no fun. It's just frustrating. Now that is all.
