We choose to make RPGs not because it is easy, but because it is hard!
Both projects have those same challenges. This one is all about building a fanbase and getting help with content creation. That will be much easier if modders can just use Godot/Blender and not learn the intricacies of my custom engine and still-evolving party/turn-based system, and I don’t have to finish it (but it’s ready and waiting if a fanbase ever materializes). I just have to make the base game, NPC AI, UIs, and content for a few demo scenarios.
And I’m not trying to make a new Skyrim to rule them all, just a small moddable RPG to get things started. Mistakes will be made, but I’m not gonna fix them if it breaks a bunch of mods, I’ll just make a new game.
