Nintendo was showing off Boom Blox at its media summit last week and IGN got to take it for another spin -- reminding them of how excited they are for this game. The Electronic Arts/Spielberg collaboration is packed with tons of content and potential. At last count there are over 400 levels. Plus, the robust level editor promises an endless amount of user-created scenarios (shared through WiiConnect24). A lot of games promise to appeal to both casual and hardcore players, but Boom Blox looks like it will deliver on that promise.
