Thank you , it makes sense now.
Perhaps calling this game executer or game starter could avoid confusion with usual ‘game launcher’ everyone is used to see in games.
On a side note knowing that you guys are considering a game updater/launcher is a big hurrah! It looks like engine providers are scared to provide a solution out of box for everyone which is weird really. Knowing in depth data structure of games build with engine allows good patching methods for small memory footprints so I’m pretty sure nobody could do something better than Epic on that matter.
How about adding this on Trello ?
