According to an article on www.develop-online.net, Crytek wants to join Epic Games with the Unreal Development Kit and Unity with it’s free edition, and also plans on releasing a “free to use” version of it’s upcoming CryEngine3! It is not yet clear, how the enduser license terms will be, but I bet they’ll be something like the ones Epic offers. Which again is very generous in my opinion.
This could also get interesting for my thesis, if it arrives soon enough. As stated in Rapid Prototyping Tool Investigation, I already cover Unreal Development Kit and Unity. The CryEngine would perfectly fit into that structure. But I guess it won’t be released within the next fex months…
