Most of the basic functionality is there, but it’s missing:
1) Ability to complete a quest, carry on to the next quest, maintain state cross-quest, save/load progress, related menu system.
2) Quest-specific logic.  I plan to implement a scripting interface as an extension to HeroScribe XML.
3) Quest-specific monsters, monster spells
4) AI has much room for improvement.
5) Sound effects.

So it’s more of a prototype than a complete game, but enough of it’s working that you can at least get a feel for it.

HeroQuest UE4 package 2019-04-18

The download (Win64.exe) is a self-extracting executable package built for Windows (64-bit).  I can post other platforms if someone requests it.  I’ve also included my modified HeroScribe package (HeroScribePem.exe) (HeroScribePem.jar requires Java) with XML map files (xml sub-folder).

If you have basic programming skills (or know someone) and are motivated to contribute, please contact me.  You don’t necessarily need to know UE4 or C++ (or Blueprints), but you’d need sufficient skill in OO programming (eg Java, C#, Python) (and are motivated to learn).
