I'm a user of the Godot Game Engine. So if I would win, the prices would bring me nothing. What would happen then with the price? Would the runner-up get it (if he uses Unity)?
We'll stick with what the rules say - the winner will receive the asset bundle, and it's up to you what you want to do with it. Whether that means passing it onto the next ranked person or your friends, it's yours to do with what you want!
Godot is for me the better Unity alternative. It has a very strong 2D Engine, but a weak 3D engine. For now Unity is the better 3D engine. But with Godot 4.0. that will (hopefully) change!
