Ok, so I got all 1st Descent quests, bit and expansions and I was wondering how can they be played using 2nd edition rules. And i thought that I will throw out monsers limits so Overlord starts with all monsters on board like there are shown. And Heores have conquest tokens and each time a hero is KO they lose one conquest if they ever lose all conquest tokens they lose the game. Overlord can't spawn monsters. Wht do You think about those house rules? Will those be playable?

Cheers

Could work. I've got a similar project on the go which more or less covers the same ground you mentioned here. I think it will work reasonably well.

You'll need to tackle quest-specific rules on a case-by-case basis to make them work in 2E, of course.
