I haven't played it, but given the opportunity, I'd give it a try.
Hey, I mocked a friend mercilessly for playing Tiger Woods on his PS2 -- how can you
golf on a video game? Then I spent 8 hours solid playing the damned game at his apt, and on my way home, stopped and bought a PS2 to play it.
I hope that no former SEALS/Delta guys ever overhear my enthusiastic discussions with buddies over tactical takedowns, breach and clear techniques, sniping and infiltration tactics --- that I "learned" from Rainbow Six, Splinter Cell, etc.
It's a game... chillax. You'd rather play a real guitar, go for it. I'd rather play Agusta, drive a Carrera GT and roll with an MP-5SD, Mk. 23 and MTAR into hostile territories. But I don't have the time, resources ... OK, I'll say it, skills

... to do so. So I goof off on a game for a while and get enthusiastic about it.
The South Park episode was
great!
