Now that I'm much further into the game my final verdict is 7/10. I dont think much more will change in the game to change my mind unless the ending totally blows. The actions get a bit boring/repetitive. The side games are lame. Some of them feel totally pointless and nothing but empty filler. The story is alright, the cool facial stuff becomes less important after awhile of playing and the whole point of it eventually gets kinda lost when you're busy having to read the subtitles to understand everything thats being said, instead of watching for facial expressions. Some puzzles suck as well, especially when the game actually figures them out for you.
I had a lot more fun playing GTA4.
