If you're at all interested in online gaming, you need an Xbox 360.
For starters, it's home to the most popular multiplayer games, "Halo" and "Gears of War." And its redesigned interface, the New Xbox Experience, makes it easier than ever to meet your friends (or make new ones) online. Even if you prefer playing solo, the Xbox 360 is the only console that lets you download bonus material for "Fallout 3," "Fable II" and (later this month) "Grand Theft Auto IV."
The results of Microsoft's Community Games project continue to surprise, with such clever amateur productions as "Rumble Massage," which turns the Xbox controller into a neck massager. And Xbox Live Arcade remains the premier source of downloadable original games, most costing $10.
