Hitman wasn't that linear. There was no place in SC where you could choose between two paths (backdoor or frontdoor, that kind of thing). You always had to do Exactly as the developers planned, which was kind of annoying.
A nice franchise sure, but doesn't deserve nearly the amount of hype the console fanbois heap on it.
not really a candle to metal gear solid franchise however.
Just another reason to hate the Flyers....
But as has already been said, good use of unreal engine, still runs like ass though, god knows epic can't code like carmack.
