Just a quick note, but this game is a must buy for anyone that hasn't played it. I still remember beating it when it first came out, and look forward to again... I dug the install disc's out a few months ago, and reinstalled and played through on a new tablet I'd purchased. Was still impressed, and then I found it on here. I'm sure I'll eventually pick it up here as well just to have a digital copy, it's that good.
I don't remember it being that hard, so not positive where that knock is coming from, but a great game regardless! Just be aware of the profanity, as this isn't one I'd play at work with the volume cranked up....
