I'd say howdy but RDR is not your typical Rockstar Game [Manhunt or GTA] but RDR is known for being the GAME OF THE YEAR FOR 2010. Lemme run this down for you.
RDR takes place in the territories of America where Guns are the basic necessities, and where the liers and cheaters can prosper. Your character is John Marston.
In RDR it is very different from GTA in so many different ways. The controls are different, the cheats are even planned thuroughly, and the storyline is just too epic. If you were expecting this game to be like GTA where the time of innapropriate advertisements prosper then you are wrong. There is nothing innappropriate in the game but major stereotypes. Heck you can even travel to mexico the story is too deep that you dont want to put your controller down. Physics are very realistic [jumping off a balcony and landing on your horse may hurt your crotch but it does work] Id have to give this game infinity/10 because its just requesting unlimited gameplay even with Co-Op missions on multiplayer.
