Copy arrived today.
Played for a couple of hours. It is GTA Wild West really, but that setting removes some of the annoying innovations from GTA IV, like the mobile phone.
The Dead Eye feature works nicely, at this point it just slows things down allowing you to plant a round right between the eyes. Later on it allows you to paint multiple shots, which are then delivered in rapid succession.
Scenery is amazing frankly, I found myself stopping to watch a sunset. Characters look better, and the quirks of the graphics suit this setting much better than they do Liberty City.
Despite the apparent hilarity of being bad, it's actually a pain. Being hunted down sucks, and I felt like a right idiot for killing a marshall, and it was an accident. Lassoing people is fun though. Occasionally you'll meet a marshall who has lost two prisoners, you get the option to kill them or take them alive. Don't bother with lassoing them, if you do and take them back to the marshall he just executes them anyway. Otherwise, bounty hunting is much more rewarding if you keep the bounty alive.
Hunting is quite good fun, make heavy use of the Dead Eye feature and you can bag a few deer at a time. Cougars are quite hard, and talking of killing by accident, when being attacked by a cougar I accidentally shot my horse in the back of the head. Going to need something pretty powerful to hunt the bears later on.
