The WoW auction house app has been highly successful. It depends "what the game is" as that decides platforms. They "don't have any opposition" to free-to-play.
"We do have a group within the organization that's focusing on mobile and tablet apps," Blizzard chief operating officer Paul Sams said. "Thus far it's been around our games. But that does not mean that we won't go there in the future."
"When we're deciding what games to make next, it's based upon figuring out what the gameplay experience is, what the game is," he explained.
"Then we decide what platform is most appropriate for it. So if the answer is mobile or tablet, when we're having those conversations, we'll definitely go there."
Blizzard may adopt a free-to-play model in the future but only if they're confident it's the best way for the customer to experience the product. World of Warcraft already supports a free-to-play hybrid model as it dumped a timed trial in favour of limiting features.
"It certainly is possible, if we find ourselves in that circumstance, or if we come up with a game where we think that's the right business model, the most appropriate for players to experience it." Blizzard is very busy with their 'Titan' MMO project.
"We don't have any opposition to the concept, it's just that at this point we haven't decided to make a game where that is the model. But that doesn't mean that we won't," added Sams. Do you enjoy free-to-play MMOs and their optional micro-transactions for content?
