countryside with small villages like red county in gta sa, do your own spraytags,pick up items eg bins broken car parts etc to use as thrown weapons , upgradable weapons so if you buy say a mp5 you can buy a scope,bigger clip etc to add on to it,better car damage than the prievious games so if you crash a car then fix it then crash it again you wont get exactly the same damage, bodies blood and empty clips+shellcasings dont dissapear as quicly as in other gta games,car mod shops like the ones in gta sa or saints row, drivable trains+flyable planes would be nice,when you kill an enemy their gun doesnt spin around in mid air lands on the ground, keep weapons+hide bodies in the trunk of your car,stealt kills using a knife,fibre wire or strangle them,steal from shops.
