I don't really Collect Current-Gen Games.
I have 21 Xbox games (All complete) And 6 PS2 games.
With Xbox i never trade/sell them. If it's PS2 and i don't like the game, It'll go out the door. (Smuggler's run is one) And if the game is for All three consoles (Or Just Xbox & PS2) I'll get it for Xbox.
Here is my ranking of the current consoles:
Xbox: #1
Gamecube: #2
PS2: #3
