Epic has purchased the Reality Engine outright, including intellectual property rights, trademarks, and copyrights. Epic does not intend to continue sales, development, or support of the Reality Engine, but will review its technologies for inclusion into Unreal Engine 3.
Developers who had purchased Reality Engine licenses prior to this sale will be offered upgrades to Unreal Engine 3 at significantly discounted prices and should contact licensing@epicgames.com for more details.
