Its a good RPG. But Its just not as good as Fallout. Much better games on the market.
Single player: The single player is about 40 hours long. Which is well worth the money. At first it seems pretty good with lots of excitement and shooting. But then when you start getting hard bosses. I got a bonehead which I could not kill. So it got extremely irritating which meant I had to buy a really expensive SMG to even come close to killing him. I like the twist where you get to choose from 4 different characters. With each having a special ability or Melee. I have been enjoying the single player. With 100s of guns which makes it a great customization game. You can drive. Which is an advantage over Fallout 3. I did like a lot of it. It just a little boring after a while, Which just made me Buy Red Dead.
Multiplayer: It hasn't got a multiplayer as such, Its a Co-op campaign multiplayer. So its not Team Deathmatch and stuff. Its a lot of fun playing all the missions with friends. Its a lot more exciting than playing alone. Especially as you can play with up to 4 players and its easy to find a match atm. I still think its a great game and quite unique cause not many have Co-op. Co-op persuades me to buy some games. The pure look of this was great. Its worth a try.
Good:
Great graphics, Co-op campaign, Great value for money, Exciting, Lots of guns
Bad:
Gets boring after a while, Gunplay is bad, Bosses are hard.
