Gameplay - This is second game I have ever completed (I don't usually play to finish game, just to have fun, also I mostly play games you cannot finish), and the only ones I have finished are - The Godfather II and of course this game. It only took me 5 hours, 38 minutes and 36 seconds to finish this game, but it was worth it, the gameplay is EXCELLENT, you cannot wish anything else. The only minus when playing this game were the duels, I failed to defeat the Mexican and Rattler so many times, a bit less was with the last duel (I don't remember the name of last person I had to duel, but he was that Confederacy General or something like that), so after all this I didn't find anything bad in the game. 10/10
Overall - Well, this game is simply excellent, while playing it - I really don't remember finding any bugs, just maybe a few and minor that don't actually affect anything.
