Microsoft are no stranger to bundles. Various iterations of the 360 console with a variety of games or special additions pop up every month or so. But this is the first time they've actually decided to bundle a wireless controller with games.
For $90, you get a wireless 360 controller and four Arcade games – three on disc and a code to download number four. The games are decent enough too without being spectacular - Geometry Wars 2, Lumines LIVE, BOMBERMAN LIVE are all on the disc, plus you get a code for Ms. Pac-Man.
Apparently those four games are worth $35, which makes the price of the controller even better than their 20% off deal. Pretty sweet.
