In GTA IV you can actualy watch TV and in that was very funny tv show Republican Space Rangers you could see that in youtube.
And finally i guess gta iv was the same big as gta san andreas sure sandreas look more like cartoon now because gta IV look very amazing, i did complete gta IV and after that was boring because the city is quite empty, you can't buy any buildings and many more features are missing which was in san andreas or vice city.
And the online multiplayer , you need to create quite many accounts to play that.
So that's it thanks for listening. Bye Bye
