"...The fact that [Oblivion] was well received critically, and had the sales numbers to back it up, is a very positive sign for us as we look to expand our presence there," Hines added.

He didn't disclose exactly how much business ZeniMax expects to generate from its new Asian arm, as the firm is privately held.

Bethesda's next high-profile title is Fallout 3, slated to arrive later this year in the US. ZeniMax Asia will be bringing the title to Asian territories.

Regarding the rampant piracy in Asia, Hines said it's an issue in every region of the world, not just in the East.

"It's a concern in any case, whether we were expanding there or not, so I don't know how much us expanding there changes that one way or the other.

"[Expanding] is more about our continuing desire to establish more direct relationships in a number of different territories. Obviously, the announcement about the establishment of a UK office to cover the UK/European markets was a big part of that, and this office just builds on that."
