Gun? Don't take my opinion as gospel, but I wasn't crazy about it. The game was just...okay. That's the best way for me to describe it. The fact it was set in the Old West didn't help. There was nothing truly good in comparison to open-world games like (it has to be said, even though it can't truly be compared to) the GTA games. I mean, outside of the voice acting and the fact the story missions had seriously uneven difficulty as the game progressed, there's nothing worth mentioning. I'd recommend trying it out as a rental, even though you can find it on the serious cheap for like nine bucks at Circuit City!
Thank you very much for the testimonial, my friend! I swear I am worthy of it!
