Never mind upcoming high-profile, DVD or Blu-ray based titles like Halo Wars and Street Fighter IV either. Digital is this year's watchword, as innovative Internet-only offerings like PlayStation Network's Flower—where you play the wind, blowing floating petals across verdant plains—take top billing. Thanks to downloadable custom level editors and expansions, yesterday's bestsellers are also promised second winds. See Fallout 3, presently benefiting from the free G.E.C.K. toolkit, which lets fans create new adventures and in-game objects. It's also receiving three online add-ons (Operation: Anchorage, The Pitt and Broken Steel), one per month, respectively, from January-March. Grand Theft Auto IV's downloadable episode "The Lost and Damned" arrives for the Xbox 360 on February 17. Casual portals like BigFishGames.com and MSN Games, and mobile platforms like the iPhone, whose App Store boasts over 3,000 digital diversions, will also heighten interest in value-priced, on-demand delivery.
