This idea wasstolenborrowed from Roto's thread idea. Name some games that you KNOW are bad, but you like them anyway.
Final Fight Streetwise- This game may just be GTA without cars and have a crappy camera and fighting controlls, but I just like it none the less.
Megaman X6- This game may be the black-sheep of the Megaman X series, but it's probably the hardest game in it. Me likie hard games!
Sonic Shuffle- Bitch as much as you want about how badly the AI cheats, this game is a very good contender to Mario Party.
