i played it on my ps2.
graphically it isn't very impressive. the city is ok but there isn't any lightning in the rooms. this looks just plain bad. even on a ps2 they could do it better.
but i guess it will be better on the pc. they had enough time.
if you want to know how the gameplay is, look for a review. it got between 60 and 70% in magazines. don't kill me if anyone has rated it higher.
from my point of view its just a very bad gta. the freedom, what you can do is similar to gta3.
and the fact that san andreas is coming soon to pc too there's no point of even leeching driv3r.
