By an asset's showcase map I mean something like there is an asset pack and they make a nice enviroment map in the asset pack to showcase what their asset is used for.
Secondly, yes I do mean a short game. For the third one, I just realized just now that there's no levels in adventure games 🤣.
Also if you know UE4.25, do you know how to package and upload a game to itch? Thank you!
