ROFL! Just wanted to announce that I have borrowed a PS3 and GoW3!!!
And if I can get my hands on MGS4, I will beat the only 2 PS3 games I care about and never touch one again!
I felt the same way...bought my PS3 for GOW3 and MGS4.
There have been other games i've enjoyed though. LittleBigPlanet is awesome (a must play IMO), and while it didn't get great reviews, i enjoyed Heavenly Sword (it's a short game, so it's a rental at best). The others that rated highly i felt were WAY overrated, with Resistance at the top of that pile. It is so far outclassed by Halo, Gears, etc it isn't even funny, yet the scores are similar.
Uncharted was a Tomb Raider knockoff, though did most things better than Tomb Raider has in years, and the second is as good as any action game on the 360.
