definitely more cars
extreme car customization
such as NFS style customizing Ex.. drop kit without hydraulics,
engine swaps, gloss chrome matte pearl paintjobs, stereo equip, subs, etc....
a female player would be sick as hell
if the game sucked worse than the first GTA id still get it just cause the female player
maybe the choice between male or female? such as in Fable2
more/better guns
airplanes/helicopters/tanks come back
better AI
and Liberty City got old 5 hours into GTA III.. plz no more
park ur car outside and it dont disappear.. n not those stupid red lines like in GTA IV
seasons would be great.. better weather AI..
all i can think of for now ill probably update real soon
