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.
