Alright I'll try and make this post short n sweet for you guy, as I know a lot of you don't like reading
Yes this is an idea of mine, no facts or news so leave if you're not interested.
A lot of RPG type games have similar type of things that gta has and I I've played a few that have quite good systems.
Now here is the idea.
Very similarly to how you can change the default emotion of your character what if you were able to enable it so that your character would have different words above your head. This would work similar to in RDR how your name would show above your head or your nickname eg. "sharp shooter". So my idea would be, for example to enable, "hitman" or something like "passive player".
Of course this can't stop all the random killing but it might help with misunderstandings between players defending them selves. Eh?
