Fallout New Vegas.
Low strength, perception is fine, max endurance (he's ceaseless in his xeeting), charisma is 1, int is (1.)2, low agility, I'd say higher luck given he has yet to truly suffer from pissing off the wrong person.
Primarily use guns and you HAVE to use fists or a knife when close, no point blank shots you're a real tough man with 10 strength not 2 stalker child. Any NPC conversation where you can be an asshole you can, if they say something insulting and there is an aggressive response you MUST pick it.
Specialize in survival to get that one perk (thems good eats I think it's called) where enemies drop/turn into blood sausage.
Is Pat an NCR guy? No probably a takeover ending because he's got an ego and he's the only guy to run New Vegas stalker child.
