For some reason I have the urge to endorse Godot again. If you happen to be interested in a FOSS game engine that can handle 2d and 3d, and is relatively easy to pick up and learn, you should try it. Also it's tiny and starts in less than a second.
If you've ever used XNA and were comfortable with that back in the day, FNA is basically XNA with some enhancements and single assembly portability to the big three desktop platforms and can run on Xbox and Switch
