Building on its recent video teaser, Rockstar has leaked out several more details about Grand Theft Auto IV. You'll play as Niko Bellic, an Eastern European immigrant who moves to modern-day Liberty City. Since the city will be newer than what we saw in GTA3 and Liberty City Stories, you will see a lot has changed. Overall, there will be less square footage than San Andreas, but what's there will be much richer in detail. You'll get to explore four city boroughs, plus some suburbs modeled after New Jersey. Load times are non-existent (apart from the initial game boot) and there is a multiplayer mode (though not massively so). It seems planes aren't included in this go around, but there should be no shortage of cars and motorcycles to drive. The storyline will be more flexible - allowing you the choice of interacting face to face or via cell phone, for instance - so you're not chained to specific task trees as with earlier games in the series...
