I believe the Sony PS2 represents VALUE!
The Wii while the least expensive of the next gen consoles, I still find the same issues with Nintendo that plagued the N64 and GamCube, unless your a fan of RPG's, Mario games and other Nintendo stables, its not the game console for "mature players".
The PS3 has had disappointing releases since day one, unless your a FPS fan, which I am not. I won't cover the Xbox because Windows is more than enough Microsoft in my house.
I never complained about the price of the PS3 as some others have, but neither did I feel the need to purchase one at launch or since. The Slim PS2 now $99 ($150 when I got mine) has a DEEP library of games to keep you busy for the next several years.
Bleeding Edge Graphics are nice to look at, but the overall selection of games on the PS3 is troubling. There are only four or five games that I would say are personal must buys as I'm much more of a Action/Adventure, Racer, Sports Player.
I just can't see myself and I don't use the economy as an excuse, a reason to buy a PS3 right now. Maybe when GT5 the full version is released, then I'll have to buy one...
As for what I am playing currently -
ToCA Race Driver 3 (5 out of 177 Cups, Career Mode Finished, Occasional Online Play)
