Short Story short Its a Amazing game..
Its not a hard or impossible game to play its actually just right. If you are not familiar with these types of games like Oblivion or Mass Effect then you might want to take things a little slow.. and learn your way around the gameplay.. its a quick learn..
Im nearly done with the game at about 18 hours and ive had my fair share of messing around.. mostly doing main quest.
Its a great game. It may have some bugs although I haven't encountered any thing major apart from 1 or 2 floating objects..
Overall its a great game to to do some killing and free play.. You can choose to be good or bad which results you in good or bad karma.. of course like any game with such a triat like Fable 2 if you choose to be bad people avoid you so watch out..or just shoot the sorry scum.
If you happen to of loved or liked Mass Effect or/and Oblivion this may just of been the game for you...
I suggest getting the game of the year edition as it comes with all the DLC on disc to install (Confirmed for xbox 360 unsure of other version).
