Fortunately for Rocksteady Studios, when you make a good game, good things happen. This is what exactly happened to Batman: Arkham Asylum, as some shocking new sales data has come in.
The title, in it’s first month alone, managed to sell over 2 million copies. Warner Bros. is well aware of the game’s smashing success, and are now taking DC game licences more seriously and have just created DC Entertainment.
