I'm glad I never went through that. I bought Oblivion, MotorStorm, Resistance and Virtua Fighter 5 when I first got it. Then came Ninja Gaiden Sigma, Heavenly Sword, Madden, Warhawk, etc., etc., etc. This was on top of downloaded games like Super Stardust, Blast Factor, Calling All Cars, Super Puzzlefighter HD, flOw, etc., etc., etc. Then I had all my PS2 games to finish like God of War 2, Resident Evil 5, Bully, and all the GTAs I hadn't finished.
So yeah, my PS3 has pretty much always been on since I've had it.
Now I have 15 games and I've only finished 3 of them (not counting PSN games).
I promised myself I wouldn't buy anymore until I finish a few more, but that probably won't happen. I just got Burnout and will probably pick up Turok and Haze soon...
