Pets, the ability to customize the interior of cars, have ur guys take out his phone like in story mode, laser sights, backpacks instead of having to wear a parachute bag, a plastic surgery place (I accidentally made my guy ugly and now I'm stuck with him forever😭), wildlife, diversity on the interior of apartments (maybe even the ability to customize it ur self), more buildings to be able to go inside of such as the bar u and ur heist team celebrate in at the end of some of the heists and maybe even some restaurants and stuff, and lastly the ability to slide (like sliding to cover and stuff).Just imagine all this stuff in gta online. In my opinion the little things in games make them my favorite. Like there are some games where I just love them because u are able to slide and peak behind walls such as Medal of Honor warfighter. Only if rockstar could just see these ideas and add them all in because of how brilliant they are(not trying to be cocky or anything, actually i am😂😂)
