I know BGE is dead … but here is what I am going to tell you
I watched the Into The Breach game, and a thought stroke me: only if I had their vision, I would certainly be able to implement such a game in BGE.
So, it is not about the engine, it is about the skills, hard work and dedication.
Now, I am making a game in BGE and will finish it, and publish it regardless the BGE status just to prove the point.
I will keep you posted guys!
