RDR

Is the game a waste of time or what? I can't stop killing random people that fly by on there horses. I have done some of the SP and have had a great time so far, but Free roam is the shit. I can't think of a game that has gotten this right (except World of Warcrack). I put a ton of time into that game (3 years) before I finally cancelled my account.  It would be sweet to be able to play a console game that long. I am curious if they plan on adding extra content for RDR? I haven't heard a thing! I know the game just came out but I am like that.
