Turn based RPG where it's just your character with no party?

Hey all, I'm looking for a single player turn based RPG where you only control your own character, not a party. I'm not looking for suggestions like Baldur's Gate 3 where you can choose to play solo but games where this is the intended way to play. I'm also not looking for real time with pause RPGs.

Looking for typical RPG mechanics like quests, combat, gear, upgrading etc. Any setting is grand and I'm fine with older games too. PC only. Thanks!
