As others started to talk about XCOM game type I would really love to see such course or class! Not about how to make such game but how to make that turn based mechanic (there is some youtube videos on that topic).
I have played a bit with turn based mechanics in UE4 using blue prints but used the system form asset store. The system is good but if you want to change something you have to dig deep and understand that system good.
And now I’ve got all my 3d assets from UE4 transfered to Unity (thanks to nice team who makes assets for both engines) so I’m ready to try and play with Unity a bit 🙂
