2. Mobile Multiplayer
Theres one huge reason were still coming back to GTA IV and itll no doubt be what keeps us on V when its finally out: superior-multiplayer. You know youve hit the motherload when you survey the multiplayer options in GTA IV and realise just how much there is, just how easy it is to access and just how seamlessly its integrated into the gameplay experience. From simple Deathmatch to Team Mafiya Mode to the riotous and innovative Free and Party modes (and just about everything you could wish for in-between) there are endless sleepless, bloodshot hours of fun to be had here. And with fully customizable character models and a slew of unlockable customization options theres even a justifiable reason to do it all. Theres still a hugely active community, ridiculously so in fact. I put the game on just moments ago to check the community health; I was in a ranked race in under 20 seconds. And I imagine this'll be the case work with any of the staggering amount of game modes. Thats reason enough to put it back on if you still have it, even to go out and re-buy it pre-owned if you already beat it and traded it in.
