Thoughts on a sequel / DLC:
I'd like to see another game made with this engine, but with more randomness. There's also a randomness aspect in items, which makes exploring scavenging for better quality stuff sense, but there definitely should be a xp system for opponents and some random inventory. Also lots more variety both in enemies and stuff. Story is ok, but this is really not a story, but a combat-driven game, so focusing on that aspect and exploring would make sense. Also randomization of caverns would be extremely welcome. If you guys have played any of those roguelikes (nethack, adom), starting again and again wouldn't hurt, because beginning from the very first screen you would have opportunity to enocunter something special. Currently biggest issue in Underrail replayability is that you need to go through lots of the very same content if you try different builds before you can choose for yourself on where do you want to go and what to do.
