IMO WoW is not a good game at all if you are looking for “role playing”. It’s a multiplayer online game and all the quests boil down to simple linear stories. There is very little player choice, and the other humans playing the game make it impossible to suspend your disbelief and actually imagine your character as a real person in the game world.
I would recommend Dragon Age: Origins. BioWare games in general have always been great at letting you build a character where role playing choices matter a lot. Other games I would recommend for RPGs with a capital R and a capital P:
Tyranny (choices matter a lot in this one. There are basically 4 or 5 distinct stories in the game depending on choices you make)
Fallout New Vegas (any of the fallout games are good, but this one has the best writing IMO)
Mass Effect Legendary Edition (play all three in order)
Pillars of Eternity 2
Pathfinder (Kingmaker or Wrath of the Righteous)
Divinity Original Sin 2
Baldur’s Gate 3 (Early access right now but should be releasing soon)
If price is an issue, my top recommendations are definitely Dragon Age Origins and Fallout New Vegas
