@ Che - good point. I do the same, esspecially on a first playthough. I'm worried about the story and getting through it. When I do a replay I'll go back and get all the main weapons and fight the optional bosses and that kind of thing.

I've never quite understood completionists. There are usually a few things in any of these games that I find highly tedious or annoying, and I don't quite get the guy who simply has to finish every little thing there is to do in the game. For me if I don't like doing it, I'm not bowing at the alter of the game programmer and completing some mundane task they decided to throw in there for the hell of it. I will if I want to, but not because I have to see 100% up there.
