lol all of you taking PullusPardus' comment seriously, dude obviously doesn't know what he's talking about

i'm betting you actually don't know what a game engine is.

@replies. didn't Fable games run on the Havok engine? , it says so when you start the games, i don't remember the forza one though.

That's your response? Seriously?

Well let me tell you that you'd lose that bet - I've actually made one from scratch just so you know

you wanted a response and you got it , don't complain.
