There exists an amazing open-world cowboy game filled with saloons, gambling, horse-riding and shootouts. Sadly for Activision, it's called Red Dead Redemption. Unfortunately for us, the game we're talking about here is Neversoft and Activision's Gun the first non-Tony Hawk game the former company produced in 5 years. Which you can totally tell, thanks to the dated graphics (it was simultaneously a launch title for the Xbox 360 and a late release on the original Xbox), sticky controls and one of the most ridiculous final boss-fights in history (the hardest difficulty is nigh-on unplayable without your controller being covered in 4-leaf clovers). This game doesn't leave you wanting more. The Red Dead Redemption comparison is the most appropriate as everything Gun does, RDR does bigger and better, and the final problem with Gun is that without any multiplayer or additional content, it doesn't really need subsequent attempts.
