We're not entirely clear on how all this cultural bomb terminology works. Last month, after we'd heard that Boom Blox had toppled with 60,000 in North American sales, we were more than willing to wittily label the game as "a bomb." However, EA's post-earnings conference call has now revealed that Boom Blox has sold 450,000 units since launch (no region specified). Since it's no longer a bomb, do we imply that EA and Steven Spielberg's collaboration -- considered by many reviewers to be the bomb -- has been defused? That doesn't sound like a good thing.
