Despite a slow start and some really long cut scenes (way too many for my tastes; I don't care much for stories when I'm in the mood to play games), this is a really good game. Basically an open world atmosphere set in the wild west. You've got a large number of weapons (lasso and everything even, which is fun to use) and there's a lot to do in the world they've created.
Eh, I can't be bothered trying to sell anybody on it. Just want HECK in here to talk about this shit.
