Depends what you mean by similar. Divinity Original Sin uses the same party controls and is turn based, but has a different character building system. I recall playing the first one and liking it, but that was a long time ago. I did not like the combat (armor system) of DOS2, it made all the battles feel repetitive. Writing was also not very memorable.
There are of course the original BG games, which use the same setting, but play in real time with pause and optional autopause. They are old, but on PC you can add mods which really improve the experience. And there are a lot of mods available for both BG1&2, frankly more interesting than what I could find for BG3.
