Yeah, UEFN when you dig past the surface is rough. I think it's a mix of both your reasons. UEFN seems to be a spinoff of their Fortnite Creator workshop while making use of their new Verse scripting. If this was originally only meant to mod Fortnite, I can see why it's so half baked as a Roblox competitor. You really are pulling teeth if you want to make anything other than "Fortnite but X".
