It does not really matter they could just put sea surrounding it calling it the Thames seas, after all this game is sort of fictional.
Well you have a good point there.
I think that if IV means something it means that there will be four cities or four characters with four different stories. Also I don't think that London will be the city in GTA IV cause London don't border the sea
and it would be very stupid to see the map limited by some kind of invisible wall or something.Maybe
St. Petersburg could do.That could be connected with appearance of Russian mafia in San Andreas.
EDIT:Still,England borders the sea so maybe it's going to be some kind of a fictional city based on London,if you know what I mean.
I think we can't know what's beyond space cause we have never heard of that(nobody on Earth),it's something completley new.But like one man said:
If man stops being courious,he won't be a man anymore.
Also there is many little ( i don't know how to say it on english ) organisms in smoke from cigarette.Well maybe universe is just the smoke from someone's cigarette.It's expanding and it will eventually disapear like
real smoke....
Nice look but bad choice for stunting.Someone might say you modded your bike's handling if you changed the model.Just cahnge the textures of nrg if you want to make videos.
