i think the main technical problem with GTA is the ridiculous amount of texture pop-in and aliasing, but all in all the game is great. the branching story is very awesome, as well as rewarding, and the gameplay has been polished to a shine. it's easily my favorite of the series so far, and i do think it's one of the very best games in recent memory. the hype for it was tremendous, but i really don't think that that should be some sort of stain on the game itself. to me, hating a game solely because of the hype is like hating a band solely for their fans, and i find that to be pretty arrogant (unless we're dealing with juggalos or maggots or whatever they're called, who seem like they're completely brainwashed).it's not flawless, but not many games are, and it still offers a completely unique experience that surpasses the great amount of disappointing bile i've seen come out lately.
the multiplayer also reigns supreme in my book. pulling drive-by's in team deathmatch with a group of people hanging out of the windows is tremendously satisfying (although free-for-all is where it's at), and the amount of customization is ridiculous. i met someone online who tried to argue that the game has too many options for its own good, but i think that it's worth it in order to have a long-lasting experience. it most definitely succeeds at being the next generation of GTA.
