I know we have John Marston as a father to make a character out of but I was thinking of an western style car, Revolvers and Repeaters. Also add a lasso mechanic like in RDR, but don't make it too overpowered, have it one use per 30 seconds.
What about a bandolier (I may have spelled that incorrectly) just to make you look awesome.
I took all these ideas from Red Dead Redemption, and I thought that Rockstar could make this happen.
What do you guys think?
