Something really needs to be done about the online multiplayer for all the GTA:IV games. Seriously, some player xbox mods need to play these games online a little bit.
You can't even play an online free-mode anymore without having your xbox frozen only a few minutes after starting the game. The ammount of game modders in these games has gotten so bad that i've quit playing them.
People pay good money for xbox live and for these games, someone should at least help to keep them playable.
