I owned only a Gamecube for a few years, and had no plans to buy a PS2 until I played Gran Turismo 3 (should please you given your name and avatar :)). I only have 5 games for the PS2 though, GT3+4, Gradius V, R-Type Final, and Guitar Hero (and my g/f has GH2). I have 20 games for my Gamecube. I never felt that I was "missing out" as you say, but I had just entered my "petrolhead" stage and was doing a lot of autocross, even bought a 2-seater RWD convertible. A game like GT3 really spoke to me at that point in my life. :)
