In VC you were also able to eat and heal yourself. GTA is arcade, in real life there are no "heart icons", but it would be nice if you could carry a first aid kit and heal yourself when you need it most.
Totaly agree, but it would take forever to make every building accesible.
It wasn't possible in SA, and you had like max 10 interiors for hundreds of houses all over SA.
But it would be awesome if you could enter into them and climb to the top floor and snipe people from there. There should be staircases like the ones you had in VC, that hotel opposite of Malibu, where you had to photograph that politician, "Martha's mug shot" mission.
You can easily download mods to make almost any vehicle go into Transfender. There are like tons of that mod, each by another author, so it shouldn't be too hard to find one. With it you can take bikes into transfender and buy NOS, change colour, buy bass boost, or buy hydraulics.
Sure, there are lots of scenarios where you could make choices, so R* should use that.
I also had to change all the controls before playing SA, but that mouse look feature in vehicles is one of the good things.
