I've always been fond of Super Mario Land games myself.
I also liked Mario World and Mario 64.
So
1. Super Mario Land
2. Super Mario Land 2
3. Super Mario World
4. Mario 64
5. I don't know if it counts but I love the Original Super Mario Bros. Game.
Boycotting the following:
1. Yoshi: He ate my car and spit out a toaster.
2. Igglybuff: Totally false advertisement. You can have as many as you like they don't buff nothing.
3. the Terms Hardcore/Softcore... We're talking Video Games. Not Porn.
4. The term Casual as relates to Gamers: We make them sound like outsider's that happen to play games. If that were the case they'd own a PS3.
5. Donuts.... Beacause I drink Beer...... and the biggest fan of Donuts hates Beer.
6. Boycotts: Their so lame.
