I think this is the most RPG game in the history of RPGs…
I would argue, granted I don't expect many people to remember the game. Ultima Online was a very heavily inspired DnD game (at least originally). You could be anything really, including being a murder chicken. Or a dragon tamer. Or a bard that walks into a dungeon and gets everything to fight each other instead of you. BG3 really gives me a lot of nostalgic memories of playing UO.
