The only tricky part of that is when people try to do all the non-combat XP and then kill everyone when it is done. (Doubling up on XP)
I'm guilty. I'll try to persuade enemies first and if I'm successful, I'll kill them anyway. I mean, they're still bad guys, right?
I really don't think it's necessary to let us kill
everything, consequences or not... I mean, sure, in real life you could kill anyone you want,
theoretically. (Have you tested this theory?)
Is this really that important for immersion?
