Mario & Luigi
I like both of these games equally until the Wii version (Super Paper Mario) came out. That game has to be the biggest letdown ever. It played like a shitty flash game and the story forced you to go through almost half of the 100 trials??? (100 trials sucked in this game) If it weren't for that game I would have not voted and just commented about it but when this game came out I got it on release and was so mad when I saw how shit it was. Please comment if you played this game and if you thought the same.
I loved this game. I find the Gamecube games a lot more fun than most modern games, which is more than slightly sad.
