I think GTA4 should get the perfect 10
I haven't had that much fun playing a game since the Duke3D days...
I think hearing people say "its just like but better graphics" is retarded, thats how almost all games are...
with GTA, alls they do is bring what they brought previously, and add a little more
With GTA4, they added better graphics, bigger city, no load times, online (this alone is huge), huge improvements all around, etc
GTA: San Andreas did the same thing (Added Parachutes, Jetpacks, Jets, etc, etc)
What you should expect from a GTA game is:
*Slightly better graphics
*Improvements of previous features
Edit: @Kantor, god I'm totally with you with the phone in GTA4, I effing hate that thing... I wish it was more of a wide bar that came out from the bottom of the screen and had all the info you need, then hides back away... kind of like old school shooters (Duke3D/Doom/Wolfenstein/etc) where you have gun/ammo/items in a horizontal bar on the bottom
