If you’re confused about what this game is like, look up some lets plays of Divinity Original Sin or Divinity Original Sin: II. Stylistically the game are of a kind, only difference is the Divinity series is using its own RPG rules to govern the combat and dialog options where BG3 is using an adaptation of DnD 5e game rules. The reason i say check out the intellectual predecessors to this game is to not spoil any actual content in BG3.

If you watch those games be played and they seem fun to you, you’ll love BG3, if it seems foreign and confusing and not fun, then don’t play BG3–or pick up DoS and DoS:II on sale if you want to wet your beak on the type of games these are.
