I'm not too worried about the achievements. I just want to know if the gameplay is fair enough to pick it up. I'm a huge Clive Barker fan and I already read the story for Jericho and thought it was great. I just wanted to see if the gameplay is bearable enough to sit through in order to get into the story.
To be honest I just got it for the GSL, but I'm actually really enjoying it, it kind of reminds me a little of Bioshock. The graphics are pretty good, especially on some of the characters and the weapons are awesome as well, plus its kinda scary.
Hope that helps with, erm, whatever If you can pick it up cheap from anywhere (I'd say $10 or under) then buy it, otherwise I'd say rent it, as all the achievements can be gotten in one playthrough, which takes around 5-10 hours.
