Finished GTAIV last weekend, its an ok game but nowhere near the masterpiece most people claim it to be.
Gameplay isnt very varied and most missions are very samey and short, the game isnt very long either but it drags a little because of its repetitiveness, that is too bad because the parts where the game is fun are fucking awesome.
Controls are a mixed bag too, combat is usually fun but the auto aiming and cover systems are broken, driving its a bit awkward but you can get used to it so its not a big deal.
The date system is a piece of shit, really what a fucking chore its to date your stupid fucking needy friends only so they dont hate you and to give you craptastic perks that are nowhere near worth the fucking effort, again this is too bad because most of the characters are really good, it almost made me feel bad about giving them the middle finger (im sorry Brucie).
The story its good, really no complaints here, its not the best thing ever but it works, its also very funny in some parts.
In the end i did had fun with the game, i dont regret buying it but i dont think i will ever play it again 7.5 - 8.0 /10 .
