( c ) -- it offered the games I really wanted to play. Don't get me wrong, there are games I would like to play, and that I do like to play on other systems, but the Wii was the only system that I absolutely had to have.
As far as the other systems are concerned I would *also* own them if it wasn't for specific reasons:
Xbox 360: Reliability problems
PS3: No "must have" games for me, high price. I'd buy one at $400 if it had at least two games I *really* wanted and had PS2 backward compatibility.
