The game series dates back to before Tarantino was doing anything other than slinging tapes at the local video store. The trailer is a little cinema-ish but isn't that how all game trailers look these days? They actually hire outside studios to make them and they often have little to do with the game except thematically. If you are concerned, buy Return to Castle Wolfenstein for the like... five bucks or whatever it goes for now and see what the gameplay is like. I assume it will be the same but with better graphics, some updated conventions, that type of thing.
Everybody good, plenty of slaves for my robot colony?
