Mkay, I might check it out if it goes on an appropriately large discount.
The problem I have with games like Half-Life and Bioshock is that they're designed to funnel you through very specific routes with scripted events happening predictably at regular intervals. It's not corridor-shooter-restrictive, but it's restrictive nonetheless. And it's compounded by the issue I always run into with games like those, where there are routes that I think I should be able to take, but they're not what the level designer intended, so I end up getting stuck for minutes, before understanding that I'm supposed to crouch down and go through that little storm drain (as in the case of HL2). Instead of say, just climbing over a chain link fence.
Other games with this type of level design might give you a compass pointer to let you know the general direction you should be headed, and I'm not ashamed to admit that I find pacing (i.e. not getting stuck) to be improved.
