I actually bought this on Steam a while back when it was on sale. It was on a whim, and I didn't have much an idea of what to expect. The story was gripping, the atmosphere was thick and tense. I'm a sucker for "haunted house" adventure games and if you are too then this game is right up your alley. Puzzles are mostly logical, however from memory there were a few brain teasers that I might have ended up looking up the solutions for, but I have never been the best at adventure games. It took me about 6 or 7 hours to finish, from memory I only looked up 1 or 2 solutions for some of the more difficult puzzles. Highly recommended.
I spent a summer playing this years ago. I have read a few negative reviews on the web, but I really enjoyed Postal 2. For some reason I really liked exploring the game world and looking in every nook and cranny. I would suppose it's not very polished but when I played it I did not care. I had never played anything like it. It can be very violent but I remember spending a lot of time just walking around exploring!
