What's fun about MGS4? I don't like anything about it, it's a stealth game which isn't really designed as one. Everything feels so stiff, just grabbing someone from behind shouldn't be such a big deal. And it's not like I'm just bad at it or anything, I've completed MGS3, and didn't really enjoy it at all. Why can't anyone make a good stealth game? Splinter Cell sucks too. I remember playing the first Tenchu game on the PS1, and that was really fun, now it obviously looks like shit though. Haven't played any more Tenchu games.
Hitman is a really good stealth series, the stealth being focused on disguises instead of not being detected, which no one seems to be able to pull off.
