Since the DS Lite was released, a number of my friends have purchased one.
One guy, who's only other handheld was a GameBoy Color that was given to him used that he never played, had been tossing around the idea of getting a DS for awhile. When we got the DS Lites instock, he couldn't resist.
Another guy, who's never really had a handheld, was flopping between a DS Lite and a PSP. It wasn't too hard to talk him into the DS Lite.
Yet another guy, who's only other handheld was an original brick GameBoy years ago, had wanted a DS for some time and me and the first guy was able to talk him into it when the DS Lite came out.
And, finally, another guy, who's a big PC gamer and not too much else, was talked into one when he saw how much fun the four of us were having with our DSes (?).
Now, between the five of us, one cousin of the first guy on the list and a co-worker's husband, we're a mere three people short from getting together a round of ten-player Tetris. Damn, I want to try that so badly.
Anywhoo, we enjoy tons of Tetris, along with a bit of Mario Kart, Big Brain, Metroid Pinball and a bit of NSMB mini-game and Star Chaser madness. Tetris and the Star Chaser in NSMB are probably my favorites. I just wish the Star Chaser thing supported more than two players at once - that would be tons of fun.
