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?

It's my 3rd serious playthrough through Morrowind, and only now it hit me on how much it borrows from Dune :P

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!

Jupiter Hell Classic is out on Steam now. A commercial rebrand of the fangame formerly known as Doom: The Roguelike, aka DRL.
DRL is still out there, free, but if you want a slightly polished up version and to throw the developer a few bones, this is how you do it.
