San andreas, So much to do, in GTA4... you don't feel like your living, in San andreas you could head to the gym, find some easter eggs, or just search for a plane to drive.
We need more GTA games with planes
An upgradeable house like in Saints row. First it could be your basic los santos house, then you can either head up to the Holleywood-esque place and buy a new house or upgrade your first one
PLANES AND HELIS! PLANES!! :wub:
I want to join in on chases, some different reactions when arrests.
Some people could just be "Ok here is my license sir"
some could be "SCREW YOU! DAMN COPS!' and speed away.
When you frisk someone they could attack you until you kill or tase them.
