I just turned 14 in September. Red Yoshi, it's cool that your 10. I enjoy talking to younger people about Mario, expressing my feelings about it, and maybe even teaching a lesson or two!
Anyway, I've played alot of Mario games. I haven't played:
Any Mario Virtual Boy Games
Wario Land 2
Any Mario Tennis or Mario Golf
Mario & Wario (was it released here?)
There's a couple more. I have an NES. In fact, most of my knowledge comes from the NES. Some might say they are true Mario fans, and not even know that the full names are Princess Peach Toadstool, or King Bowser Koopa. I know alot about the classics, and I own an SNES, NES, GB, and a GBA that I bought on my own! All my friends have N64s, and I also own a cartoon episode, and several comics, including the ones that feature Fryguy High, and Koopa's High School Days.
