i don't know if its weird but i like my stuffs in one place as long as possible
and in terms of game dev i like stuffs i can open from steam,
if you know krita its an open source app but in steam you need to buy
i still bought the app to also support the devs,
godot engine is there blender is there krita is there aseprite also
too many reason to put the app there
you'll get an auto update you can also turn it off too
bigger community bigger forum bigger audience
steamworkshop but then again its up to the dev if theyll implement this

i like the concept of this and i hope ill see it on steam
endorse this to people make this game engine popular
