GarageGames, which licenses the Torque engine that was used to make games such as Tribes2, has lifted a restriction from their Independent Developer license, and changed the Commercial Developers license as well.
Individual developers who wanted to use the Torque engine could always pay $100 to license it, if they agreed to publish through GarageGames. Now they can publish anywhere they like, as long as their annual revenue is less than $250,000 and the engine is only used for games.
The Commercial license used to be a flat $10,000 per title; now it's just $495 per programmer seat for any application.
So if you're feeling like you want to make a 3d game all your own-- for Mac OS X, Linux, or Windows, and can't wait for the Halo Editing Kit, then maybe Torque will be right for you. Thanks MacCentral.
