yeah, next time I should probably find some people through friends locally, or I should be picked by someone if once I can make a cool little game demo... fortunately I have a friend working in the industry who might know people who know people who want to do similar crazy stuff in their spare time as me.
unfortunately he found my early works (MapBuilder1 era ~3 years ago) having very basic graphics, and asked me why I don't use UDK instead? the answer was simple, it was too difficult for me.

moreover, good artists (even if doing as a hobby) would not prefer 3dgs over other newer engines, despite 3dgs is suitable for RTS games, as this genre does not require so high graphics details. and I will mainly need artists.
probably if I would do exactly the same with UE4, they would find it more attracting and promising, despite it should miss some features currently impossible to implement with UE4 (e.g. runtime terrain deformation), but would look visually nicer than what I could ever create with 3dgs (e.g. terrain, vegetation, and lighting in general).
