So I finished Resistance 3 last night and it was pretty disappointing.

IGN seems to disagree with the length of your playtime -

10hrs vs 5hrs is a significant discrepancy. They also talk about large scale battles and bosses (also contradicting you here). Not trying to say you didn't play the game, but it seems like you either didn't get as far as you claim, or you just didn't like it.

I just went onto IGN and read their review before seeing your post and I was going to say the exact same thing.  Now Im a little confused between what IGN said about the game and what the OP said.  Guess Ill just have to read more reviews to find out...or probably just buy the game and find out for myself.  Probably the latter.
