lets think of some things that would make GTA kooler and more realistic heres a list of things i think:
Have kids
have dogs and cats
be able to buy shit and design ur house like the sims
be able to sit and watch tv and just shit like that just add simish feats.
be able to get married lol
be able to be in any gang other then one or better yet be able to start ur own and give it a name and color
be able to design ur character from head to foot
be able to design ur own clothes with logos n shit / same with tatooes maybe like type in a word and have it transform it into bubble letters
other then gang work maybe have a career i know it sounds gay but i mean like be a rapper or a big drug dealer (good career choice lmao)
be able to take and sell drugs
j................ok thats enough for now but just pretty much make it more realistic and add sim like shit to it
