Just a overall fun game.
Anyways, it's a open world western similar to RDR. You have side quests like bounties, ranch hand, poker tournaments, hunting, delivery missions, and helping the law marshals out. I found a lot of these side missions fun to do, and they added a good amount of game play to the game. You could breeze through the story in about 5-6 hours. But if you are like me, you normally take your time, do the side missions, earn money for upgrading your guns/items and just not in a rush to beat games, the game could last you 10+ hours. You get pistols, rifles, shotguns, sniper rifles, dynamite, fire bottles, knifes, and tomahawks. You get to "fast draw" with your pistol which slows time down, and switches to a FPS point of view. While doing this you get to auto target enemies by flicking your left analogue stick towards the enemy. It's a very good technique for killing groups of people. The shotguns work good on groups of people too. There are quite a bit of bosses to beat too.
The story is pretty cool. About a guy seeking the truth about his father's murder, and at the same time you are out for vengeance. The world map is pretty small, but since there isn't any fast travel, it makes going place to place easy. There are a lot of secrets to find too like mining all the gold around the world map.
If you are going back to older generation games, this is one you should buy. It is very similar to RDR, but on a smaller scale. At a small price tag, you have nothing to lose, it's a good game.
