The rare trifecta of a great game coupled with a great license and pushed with great marketing is turning into significant, great sales for Eidos with Batman: Arkham Asylum.

From IndustryGamers:

Earlier this month it was reported that Batman: Arkham Asylum had sold close to 2 million copies in its first month. Today Eidos and Warner Bros. Interactive Entertainment officially confirmed that the game has shipped over 2.5 million copies since launch. Superhero games haven’t exactly had a great track record (with the Superman games being the worst of the bunch), but Arkham Asylum has been lavished with praise, garnering a Metacritic score in the 90s.

Of course, not every product has that rare confluence, and there’s no way to tell if one of these items impacted sales a lot more than another aspect; for example, a Batman game would sell well regardless of its quality. The question is how well, and we hope to answer that question in an upcoming feature here on the site.
