Unreal seems to be difficult to get installed in linux where as RPG Maker can run in Steam with the Proton Windows emulation and Godot is native. I honestly would prefer to stick with something open source like Godot due to the lower risk of someone at Epic or another Unity Debacle.
Mostly I am thinking of creating some RPG story type games mostly to try and get an ide of how such things go. Might be interesting.
