Thanks guys, good feedback which has almost made up my mind for me that i'll send it back.
Because i rent games i give them less chance to impress me than if i'd bought them, as i've not lost anything at the end of the day. If i'd paid my hard-earned for it, i'd try to make myself like it.
I'm not stuck, just bored of having to keep replaying sections. The most recent example is we've only been outside the city walls for a short while, and i've just been separated from the girls as the roof collapsed, so i have to sneak through a few rooms to find my way back to them. The specific part that annoyed me is that there's some good stuff to scavenge before a hard section, so every time i die i have to keep going to scavenge the same stuff again. Wasting my time!
