Wow. Simply amazing. I would give it a 10, but want to leave room for some upcoming games I'm looking forward to.
This game certainly solidifies the reputation of Rockstar as being the preeminent powerhouse at crafting thoroughly immersive and visually stunning gameplay experiences. If you are even thinking twice about geting this game due to the old west theme, take my word for it; it is awesome. I have never enjoyed western movies (with the exception of Tombstone), and hate country music, but this game sucks you right into the era. It's like PLAYING the movie tombstone.
Haven't had too long to play it yet, but it's clearly going to be the new crack of video games! I'd write more, but gotta get back on the stick! Mount up, and enjoy y'all!!
