Epic president Mike Capps has said the developer is holding off on developing titles for Vita until the platform sees success in the Western markets.
"We're not currently making a Vita game, I'm not sure how well it's going to be accepted in our Western market which is primarily where our games sell," he told GI (thanks Shack).
Why such reservation? Smartphones.
"It's a really cool platform, but I have a phone, and it's really hard to compete with that," added Capps.
Despite holing off on game development, the studio was quick to get the Unreal Engine up and running on the portable for the benefit of its licensees.
"We got our tech on it really early. We were, I think, one of the very first people to get one and work with it and we were on stage at the launch, because we have a lot of licensees who are curious about it and so we did the first part," Capps went on.
"But we can't really fully support that platform unless we're shipping our own games, that's how we know we know that platform, and it's really important for us to do that.
"We're pretty honest with folks and say 'you can have the Vita code we've got but this is not the same as us having shipped on Xbox or iPhone.' It's the same business decision I think that anybody makes, is this a platform for me?"
Vita does, however, already have a pretty strong line-up of launch titles, including 12 first-party games confirmed for its February 22 launch in EU, in addition to several third-party titles.
