Thanks! This is just what I needed. I had a couple of ideas: 1) let the user pick what kind of mobs he wants to fight 2) put down triggers (place markers) to cause surprises 3) let the user select a difficulty on top of the normal slider.
"As for loot while wandering in editor, just start from the beginning of the story and should be in a deserted Enclave full of NPC to sell things to, buy from, etc." Hmm, I haven't seen that. I start a quest, add a map, put down some NPC's, mobs, etc. When I start to play it, there are no other NPC's, no vendors, etc.
