I have seen some newer games with DM features and that's not exactly what I would say I'm trying to suggest. I love playing games for their story and being able to experience a solo campaign and I think Larian studios excels at creating that experience already. I just would like to see a multiplayer mode where the players are not "chosen" or special and the exploration and adventuring are just raw and open for replayability.

Like I imagine a Balder's Gate or divinity game where 2 to 4 players can start in a city and then choose where to go and what quests to take. I'm obviously not a game developer and don't know how hard this would be to accomplish, but I just think if the world map is already built and the quests already exist, then it would be like changing the starting point of the players and letting them branch out from there.
