Blizzard has explained its rationale for expanding World of Warcraft’s in-game store.

“For players who are already interested in the in-game items we offer, such as Pet Store pets and mounts, the benefits of an in-game store are pretty clear,” wrote community manager Bashiok on the Battle.net forums.

“We think everyone would appreciate the convenience of being able to make such purchases without having to leave the game, and ultimately that’s our long-term goal for the system, though there’s quite a bit of work involved in retrofitting those existing items into the new system.”

The new items will be tested in Asian regions first, and include an experience buff to assist with the levelling process, as well as an alternate way to acquire Lesser Charms of Good Fortune.

“We’ve had a lot of requests from players in different regions for convenience-oriented items such as these, and as with other new ideas we’ve introduced as WoW has evolved – including Pet Store pets, mounts, and more – your feedback plays a hugely important part in determining what we add to the game,” said Bashiok.

“Ultimately it’s still too early in the process to make any final determinations about our plans, but in the meantime, we hope you’ll check out the in-game store once it’s implemented on the Public Test Realm and let us know what you think.”

News of the store expansion broke last week with the discovery of a spell that doubled the speed of experience accumulation, along with a note referring to an in-game store.
