I tried it out on PC first. I had to DL a pirated copy of it because Valve decided to be jerks and remove the demos from XBL and Steam, but I was hooked very easily. I quickly went and ordered a copy for the 360 (always looking for those gamerpoints) and have enjoyed it greatly.
I am looking for people though who actually know HOW to play the game and don't think they're Gordon Freeman since it's a Source-based game. We should all add each other and party up for some games. My gamertag is the same as my name here.
UGH! I just played a game and, against logic, all the players seemed to make it a point to DISTURB the witch INTENTIONALLY, as opposed to avoiding them...
