I'll write my story also, so that maybe Nintendo gets a picture of it's older gamers.
I'm 29, married and I've always been a Nintendo fan (NES, SNES, N64, GBA and now the Cube). But, I also often buy the other consoles 'cause I want to see what else is there (Atari, coleco, sega master, Genesis and know PS2). My favorite games are always on Nintendo's machines. But, once and a while I have to much money and I need to get more games (and Nintendo doesn't supply enough games!) so I go out and buy another console. That's why I bought last june the PS2 with GTA (I wanted to play that game!). And I must say that GTA is a great game and I'm not talking about hitting on old people. The sript is good and when I have friends over we just play vigilenty missions or we try and get the highest wanted level (fun party game!).
And here's my game list in order of purchase :
Luigi's Mansion - great game, to small
Pikmin - great game
Super Monkey Ball - great game
Star Ware Rogue Squadron 2 - great game
Resident Evil - nice graphics, boring puzzles
Ethernal Darkness - Awesome game, great storyline
---Slow time for Nintendo, so I went and got the PS2---
Super Mario Sunshine - great game
TimeSplitters 2 - Awesome game, lot's of extras
Animal Crossing - Awesome game, just stoped playing after 3 months of everyday play
Super Monkey Ball 2 - great game, I liked #1 better
James Bond Agent Under Fire - boring game, to lineare
Metroid Prime - Awesome game
Curbivore - my worst purchase

Zelda Bonus Disk (Oot &MQ) - great classic
