Downloadable games are really clicking this generation. It's easy to see why, too -- it's the lazy way to play. Hell, all you have to do is hop online, push a button, and boom, you're minutes away from getting your game on. Right now, all three of the major consoles are vying for your virtual bucks. Each one offers easy-to-play classics and smaller titles designed to quickly kill time. Of course, not all of these attractive appetizers will fill your gaming belly like a meaty retail game. Or at least that's the case now, though Sony might be changing the way the menu is written with upcoming main-course titles like Gran Turismo 5: Prologue and SOCOM: Confrontation.
