Just buy the damn thing! It's the cheapest console on the market, and you'll come to realize that it's the best! I could name a small number of games that would keep me busy for months, and a much less rabid video game fanatic busy for probably twice as long.

What do you like? Blowing shit up?

Metroid Prime, Metal Arms: Glitch In The System or P.N. 03

Adventure games?

Zelda: Wind Waker, Star Fox Adventures or Beyond Good And Evil

Platformers more your thing?

Viewtiful Joe, Mario Sunshine or Vexx will suit your needs with flying colors.

RPGs?

Skies of Arcadia Legends, Summoner: A Goddess Reborn or Tales of Symphonia.

You want stuff that will scare the hell out of you?

Eternal Darkness, Resident Evil or Resident Evil Zero.

Racing Games?

F-Zero GX, Extreme-G 3 or Mario Kart: Double Dash!!!

There's a ton more stuff than that, and everything I've mentioned is top-tier quality. Better design and innovation than anything else out there, and technologically more impressive than PS2 games. Pick it up. You won't be disappointed.
