An isometric or similar perspective CRPG with turn based combat, and the freedom to build characters and think up alternate ways to complete quests that is comparable to the original Fallout games.

Set in a slick scifi space opera, adventure universe. Where the player character controls their own ship and can fly from place to place, while also upgrading the ship and participating in space battles (also turn based). Lots of main planets to explore with bespoke elements, but also a good amount of tasteful procedural generation of minor planets to help fill out the game world.

A few games come close, but nothing quite gives me Classic Fallout + Mass Effect + No Man’s Sky that I want.

Warcraft III had maps called "RP Maps", which were kindof like D&D placing things, except everyone had the same control over the map. So it became more about telling a story rather than one person leading a group's game for them.

When wc3 kindof died off that kindof game along with many others didn't leave it. SCII mapmakers tried but it had issues with the complexity, and with SCII not allowing traditional saving for long sessions.

A lot of sandbox games are cool, but built around FPS engines instead of anything third person.

Person has an idea for an X-men RPG, conceptualised a little too well and loves it so much they cursed themselves with the awareness of difficulty of game development and it's non-existence.

Decides to make a video and spread the curse to X-men and JRPG fans alike.
