Fallout: New Vegas 9/10
Amazing game, it's rare you get a third/first person RPG without sacrificing the RP part of it. New Vegas definitely nails the roleplay. You can side with one of the three major powers in the Mojave or kill them all and cannibalise their corpses. Almost everyone can be killed (Except your companions who are currently following you on normal mode and Yes Man who is essentially malware that jumps from one robot to another). The only downside is that many mountains have invisible walls on them. Which means you usually have to take the road.
But yeah, amazing game. I'd recommend it to anyone who loves RPG's of any stripe.
