Double Fine's Tim Schafer's said on the company's site that the developer's publishers don't release PC versions of its games because there's not enough return.
"As a developer we do not have final say in the SKU plan for our games. That is the decision of the person investing the money, i.e. the publisher," said Schafer.
"We have much of the technology in place to produce PC versions of all these games, but there is still some more work required to make them shippable and that costs money. So far, our publishers have not elected to fund that work. Not because they hate PC gamers, but because they don't see enough financial reward.
"Double Fine does care about PC gamers, and we always push for a PC version, and will continue to do so in the future. If we ever get super stinking rich here, with enough money to fund PC versions of our games, then we will go back and make them ourselves! Oh man, wouldn't that be cool?"
Double Fine's latest downloadable title, Stacking, releases for XBLA and PSN next spring via THQ.
