I'm afraid I don't know anything about Game Maker Studio 2, what I would say though is you should get into Godot or Unity sooner rather than later. Other lesser known software tend to not be as feature rich as either of these engines and you may find yourself pretty limited by them.
If we're talking 3D then yes, a simple plane with it's own collider and tag or however you assign objects in Gamer Maker Studio 2. I'm recommending the other engines because in Unity at least they have a built in physics material that enables sliding behaviour and so on without any code you just need to fiddle with some settings.
RE: Does anyone have a subject they're particularly stuck on with games development or a genre they want a write up for that there aren't many tutorials on?
