The only two things I could think of when watching this trailer were “Holy shit, game CGI graphics have come a long way!” and “Wubwubwubwub yeahhhhh drop that bass.”
(For the record, I enjoyed Far Cry 2. It doesn’t look like this sequel has anything to do with the previous games, though. Then again, you can’t really divine much from this movie trailer, anyway, as there’s no gameplay shown in it.)
