GTA is for all fields. If you feel like doing a mission, so be it. if you feel like killing cops, so be it. If you feel like wasting your money on hookers, so be it.
Its a game, and the way you play it to enjoy it, should be up to the individual. If an aspect of the game does not interest you, there are many others that will, otherwise, you would be playing a different game.
Personally, i enjoy all aspects of the game. More recently, after my killing spree's i have begun to do the missions, and i enjoy them very much. I just like to do random things between the missions
.
I agree, that at some stage of the GTA franchise, it seemed like they wanted to throw in a level of realism and that seemed fine with me (pumping weights, eating etc etc), but i much rather the way it is now. I already waste a lot of hours on the game and do not see the reason why i need to pump iron to kill random people with my sawn-off shotgun.
Sneaking into the Military airbase and stealing a fighter jet and loosing the wanted level when you hit the ceiling is awesome fun. I can't seem to get into a tank yet without being blown up. Maybe ill start giving the console commands a shot, painkiller me up!
CAPSLOCKSTUCK, love your yacht! Wish you can hook up a jetski to the back of the Yacht, so when you arrive close to somewhere, you can use the jetski to go the rest of the distance.
