Other great games with similar play styles are:
Red faction (open world shooter with loadsof destruction
Crackdown (gta type with super hero like abilities)
Red dead redemption (open world western shooter)
The witcher 2 (open world RPG,and it's epic!)
Dragons Dogma (open world RPG)
Borderlands (sorta like a half ass open world? With lots of shooting and RPG elements) I guess that thebest way to describe it.
Two worlds 2 (a decent open world RPG)
Sacred 2 (a decnt RPG kinda similar to diablo when considering the camera view and lots of looting)
All good choices, except The Witcher 2 isn't an open world RPG at all, it's very linear
