Namco Bandai's VP of Marketing Charlson Choi tells website siliconera.com that the company knows why Enslaved struggled to move 500k copies- Christmas.
Choi says that the game, a new IP for Namco, was simply released at the wrong time of year. The pre-Holiday season is the biggest time of the year for game releases- or more specifically: monster, already established, game releases.
Enslaved had everything going for it other than that last part above. For fans of the game, that's a load off as Namco says to expect some news regarding the franchise. Not letting a quality title die because of so-so sales?
