The only thing growing exponentially in genAI is energy consumption and the volume of executive bullshit ahead of the next funding round.

Just on time for Christmas Eve I've defeated Hircine and finished Morrowind in my quest to complete the Elder Scrolls. I'll take a breather and later head to Oblivion! Merry Christmas πŸŽ„ :D

We promised more mechanical transparency, and we're delivering - even in the most esoteric of places! #JupiterHellClassic

Vibe coding basically gives the effect of a client constantly requesting new requirements to a project without allocating refactoring time.

The Jupiter Hell Classic equivalent of a chess puzzle: What do you do to save the loot? Does it change depending on class/traits? :P

As a few of you know I'm on a quest to finish the entirety of the main Elder Scrolls series - Morrowind has been completed, the Tribunal expansion is next!

Tenerife, Teide peak (3718m). Really needed some time off!

I am actively searching now for funding for AliensRL to give it the JH quality treatment :P

Add in a very dark fantasy setting, more randomness in environments/missions than your average ARPG, and multiple characters within the same "run"...

15.11.2025 22:13 β€” πŸ‘ 2    πŸ” 0    πŸ’¬ 0    πŸ“Œ 0

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.

15.11.2025 22:08 β€” πŸ‘ 3    πŸ” 0    πŸ’¬ 1    πŸ“Œ 0

Indeed, but I think the game would be even better if it would be balanced around that :)

It's the classic Necromunda campaign issue. Failure leads to harder time playing which spirals. To play well this must balance the opposite - classic rubberbanding solution - after failure it should be a bit easier to claw back.

15.11.2025 14:53 β€” πŸ‘ 2    πŸ” 0    πŸ’¬ 0    πŸ“Œ 0

Yes, but the game is not designed for permadeath and is unnecessarily frustrating in many aspects. You can play any game permadeath, but most are less or more frustrating.

15.11.2025 14:47 β€” πŸ‘ 3    πŸ” 0    πŸ’¬ 0    πŸ“Œ 0

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.

Visuals think Ishar, combat think M&M 4-5, with DCSS-style richness of random dungeons and JH-style streamlining.

14.11.2025 21:44 β€” πŸ‘ 5    πŸ” 0    πŸ’¬ 1    πŸ“Œ 0

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.

14.11.2025 21:41 β€” πŸ‘ 15    πŸ” 0    πŸ’¬ 1    πŸ“Œ 0

I need a genre that I'm vaguely familiar with though, BH is farr from it :P

I'd veer to single character myself also.

There isn't much overlap in the design space :P

13.11.2025 22:28 β€” πŸ‘ 0    πŸ” 0    πŸ’¬ 1    πŸ“Œ 0

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?
