I can't get enough of this game, it runs nicely on my older system, and is really fun and the experience the game gives you, is just awesome. Sitting around a camp-fire listening to stories or sing along. Or shooting up an oil rig and running from the law, Just an overall fun experience.
Pros: you can hit escape any time and the game will pause, so if you need to run somewhere, you don't have to wait for a point where you can pause.
Cons: It's a huge download, 120gig so just look out for that,
