Here’s a suggestion. Bevy should invest in a couple of moderately complex sample games that are maintained. I think a critical failure of Unity is their refusal “eat their own dog food” so to speak.
My recommendation is to put ZERO effort into game design here. Build a few straight clones (within legal bounds, of course).
PacMan, Link to the Past, Doom, Quake, Threes, Angry Birds, etc. Pick like 3 that represent a sample of 2D, 3D, etc.
And I mean a “full” clone, in terms of functionality although not content. By that I mean main menus, persistent high scores, multiple levels, numerous scenes/levels, etc.
I’m extremely confident this will pay off. You could debate whether t should be done sooner or later. I recommend resisting the urge to pushing until more systems stabilize. You need “real” examples to help stabilize and discover the warts.
