My friend brought this game over Friday night and I played it for a while and for Rockstar Games (a game company I don't care too much for), I didn't mind it. Although it did have a GTA feel to it, but Western themed. A good rent, but not for purchase for me.
I enjoyed the music and the environments are GIANT which is very nice to see.
As I said, tonnes of fun, but in my opinion not worth buying.
