The game is very much like Fable 1&2 but more refined, IMO. Ive gotten about 6 hours into the game from casual playing and its still pretty fun so I would recommend it. The graphics have to be set quite low and I have a medium grade computer (however I need a new graphics card). Even with low graphic settings the game is still very appealing and open. The story allows you to choose dialogue however its still relatively linear. I like it nonetheless, check it out if you liked the Fable series you'll no doubt have fun with Venetica.
edit: This isnt my screenshot, I just found it. So far none of the enemies ive fought have been over-sized like this guy.. didnt know there was gonna be a 3-5 story tall beast to kill but hey that sounds fun eh? lol
