So out of curiosity how may of us INDIE game devs have actually finished a project?
What answers do you expect? Unless there is some official list we can only guess… I would say about 200.000 since there is reaaaally much indie stuff in the app stores.
Scroll down to UE4, I think it may help
he has not asked about UE4 games. He has not even asked about released games, only about finished games.
