3rd for me too,.. its overall a better game than others.
but I love the first one, its graphics are state of the art. Loading times was one of the things that more annoyed me. Playability is questionable, but its graphics made me want to play it. I finished without cheat, but just one time, and having finished others times with cheat.
the second was a deception for me, I hoped a lot.. and I loved the weapon the Beast used in the screenshots available. But when I got a copy it was pants. I even dont liked the graphics.
