Please please please let there be features like controlling the size and weight of the character by going to the gym,lifting weights etc muscular figure,also tattoos like in San Andreas would be a great addition.Features like this give the game more realism.another great new feature would be being able to actually purchase a house and car,and have to fill a car with gas,more realistic ways to spend money in the game
Also be able to rob houses and banks outside of story mode,gta iv became repetitive and boring outside storyline,attach a trailer to a truck etc and customize vehicles
