THPS 1&2 were made using Neversoft's in house engine and from 3 onward they used Renderware. Neversoft are actually talented developers. I have nothing against Unreal, I've used it before and it's a great engine. However when I started up THPS HD and saw the Unreal logo, I cringed and knew straight away that it was the wrong engine for a THPS game. Most of the problems I thought it would have, it has. Robomodo have done nothing but rape the series. THPS HD doesn't have the soul of the earlier games at all, they did the bare minimum with this remake. Sorry for the rant but it's hard seeing one of your favorite series get killed like this.
