a few people are saying that they dont think its liberty city,but new york...as the land marks,and rockstar are trying to fool them
from all the trailers on the net,it doesnt look as good as on my TV downloaded from xbox live marketplace
and there i have had a better time pausing the trailer and looking for clues,at first i thought it wasnt gonna be liberty city(see my post some way above),despite it saying so on the boat(cos it could of come from liberty city and docked at this city),and it says liberteen on a building..or liberty tree in another sign...could be rockstar fooling us(making us go round in circles)...but i think it will be set in liberty city,and its the ferry terminal scene that won me over....over to the right in that part it says liberty ...but above the ferry terminal sign(where the 'R' is missing from ferry)above that is another sign.....with the letters ' iber y'...the L and T missing.
the statue of 'liberty' is another sure sign...but then again they had a london addon pack set in the '60s,so it isnt wise to rule out New York
and i guess those rumours about it being set in the 70's were wrong,that car definetly looks like it came after the 70s..although the russians (foreign)clothing does not...but then again he is russian or foreign
