If only I was an artist this would make for a great SC mod.
But I do not believe when CIG went with Amazon they got the right to sub license the engine. While the the modifications they made to it are theirs I am not sure it would benefit them to try and sell it as a add on. On top of that a lot of what they have done with SC unreal has been adding to their engine already.
Now that SW is Disney, I highly doubt they would let you make and publish such a mod
I saw on YouTube that some good folks are building jedi knight in unreal engine, and once it gets into a playable state I'm pretty sure they'll get their c&d letter in the mail.
Yeah I guess they won't be allowed to sell the engine, but I'm hoping that they could arrange a deal that at least trickles them some small percentage in case Amazon licenses the engine to someone with CIG's improvements in it.
Also, they got the server / multi-player tech that they built, I guess they could license that out in some form? I don't know how much of that is separate to lumberyard though.
