Let's cut to the chase... this game is brilliant!!
The main story is very good, the graphics are excellent and the controls are simple and easy to undertstand... however... the thing I like most about this game is the amount of ADDITIONAL things you can do over and above the main storyline... You can literally go anywhere you want... Enter any building, talk to all the locals, get married and loads of other things... I actually spent three hours wandering about talking to people, stealing from houses, buying things and working as a blacksmith... then I remembered I was mid-mission and had to be somewhere!
Your actions also change the way people feel about you as well as your actual appearance... You decide who you want to be... good guy or bad guy.
If you've got plenty of time to kill this is definately the game for you. I highly reccommend this and if you don't buy it... well shame on you!
