Kind of surprising that in 29 replies no one has gotten it right:
Immersion, and 1999. Those are the two best of the past decade. And I believe you can get a double DVD set that has 1999 and Walls of Freedom very cheaply (not sure if Immersion is easy to get).
In fact, if you buy Immersion/1999 and don't like either one, I'll pay whatever it cost you.
Of course Blizzard is a classic and some of the other movies listed here are excellent, but Immersion and 1999 are the only two that really carry on the feel established by Stump in Blizzard.
