So yeah the third idea is the ARPG one - here the permafailure design would have to be more loose as the single character vs game length would be painful. So we keep an in-world explanation of rebirth when attempting 2-3 hour max missions. Death wipes new loot and a part of the new XP.

Other idea was an XCom-like but with permafailure. No loading previous save files, but lethality would be toned down (think Necromunda out of action + injury).
Dealing with missions gone south, cutting losses, comebacks, long-term injury, etc is an untapped area in XCom-likes.

One idea I'm playing around since a long time is merging the classic Dungeon Hack-style 90-degrees rotation dungeon crawler with a traditional DCSS-style roguelike game. Care would have to be taken to make the early game smooth, but I think there's potential.

My original idea was to start with roguelikes and then bring the design ideas to other genres. I see that was done without me already :P. So which merge should I go for first - blobber dungeon crawlers? Action RPGs? Or Xcom-likes?

This convo I had highlights the difference in what "respect your time" means in games.

A lot of players want to trade time for in-game progress. It's purely transactional: 1 hour = 1 progress

But I want to feel like my actions matter i.e. what I do with time creates progress, not time itself.

Some of you know of my quest to complete the Elder Scrolls back to back... I just finished Daggerfall!
A short break and I will head to Morrowind next!
(to those curious - I went with the Underking...)

A demake of a remake of a roguelike unmake. It's okay to be confused, but Jupiter Hell Classic is a cool roguelike now in Early Access on Steam.

This is *the* modern roguelike (actual roguelike) with a lot of really cool design happening: my fave crafting of any game (tied with Teleglitch), nice/easy UI (this is insanely rare in this genre), a chain of secrets threaded through the game, etc.. definitely check this one out!
