hm, well I bought GoW collection, and am enjoying GoW1 now... it's simple, satisfying gameplay, and the controls seem very good. I like the "loose but responsive" feel. It's a damn good thing it won't let you fall off edges when you're not supposed to, though, because I'd die every 5 seconds if it did...
The visual don't seem too bad really, especially considering it's really a PS2 game! Certainly not "annoying bad".
Also cheaper than other PS3 games, and you get two for that price!
