So, it's been out for a week.
I got it the day of release but have only had time to play it for a couple of hours. I'm loving it though. The gameplay is typically shallow for an id game, but more than makes up for it in gunplay and ambushes.
I think a remake of Resident Evil is due from the mod community
With full freedom of movement.
Between that and Quake IV (by Raven this time) it's going to be a nice winter for playing cool mods.
