In the game, there is not much to say, it makes quite a lot of fun, especially if one gambles online with friends, because Rockstar really decent job has done. And do not worry, the online mode is much better than in GTA IV! :)
Of course like any other game also, one or the other thing that one annoying over time, such as the dämmliche horse that you whistle to him and it for some reason, then running away from one. Or that you can not skip the collecting of certain herbs and animals, the sequence, since one already so something must collect, if you want to reach 100%.
Otherwise, I would recommend this game only.
