Update on CryTek vs CIG.
In short CryTek have moved to dismiss the case, CIG want it to continue..
Why do CryTek want to end it here? its to do with Squadron 42, CryTek want to dismiss the old case and build a new case, their contention now is that CIG claimed they moved from Cryengine to Lumberyard for the game when in fact they have not, CryTek say they have new evidence to prove this and are waiting for Squadron 42 to be released, so they can prove it is in fact Cryengine not Lumberyard.
CIG seemingly preempting this have conceded the code is the same, which it is, Lumberyard and Cryengine are the same engine, Lumberyard is Cryengine under another name, but CIG maintain it is the Lumberyard version of the engine.
I use both, Amazon have made some cosmetic UI changes to Cryengine and built a custom plugin system around it, other than that, they are the same engine, its going to be difficult to tell them apart at a code level.
