DOS1 is really similar but the writing isn't as good. BG3 is buggy as hell and not done since it's early access but the writing is way better and the game has a similar feel but the combat is really really different. If you're open to real time with pause games, pillars of eternity or dragon age origins could be what you're looking for. People also recommend Pathfinder Kingmaker which has a turn based mode but the writing is awful, the system rules are arcane, sometimes kingdom management bugs force you to go back to a save like 12 hours before or get an arbitrary game over, and also most of the encounters are fighting the most obnoxious possible trash mobs over and over again.
