I could imagine there being a cause for FreeCAD if it ever gets accepted as the "we don't want to pay for AutoCAD" solution in some less developed nation education system.
On a more optimistic note, it does seem to be improving with time. Maybe one day it'll have the Blender transformation happen to it.
But you can make games that much more interesting if your algorithms are on point.
Otherwise it's all "well I don't know why it generated map that's insane". Or "well AI has this weird bug but I don't understand where it's coming from".
