I think their biggest problem is how to do time in MP, which is the same engine as SP, but allows independent control of each player's time stream. If one player is exploring at, say, 5 real-world mins per game hour, while a second player decides to go into TB mode, where time essentially stops, occasionally advancing by 6 game seconds in a much greater amount of real-world time, then you are in a mess very quickly.
They could make SP and MP modes different at fairly significant development cost, but I don;t think they want to. They could also make TB apply to all players in MP whenever it applies to any one player, but I don't think they want to do that either.
If someone here that wants D/N can suggest a good mechanism for MP, then maybe Larian mat reconsider.
Addressed in the very first page of the thread (and several times before in the past):
it was a very simple limitation to work around in the end: "Freeze the clock for everyone when one of the players is in turn based mode. Make it march again when all the players are in real time".
I mean, the limitation that everyone needs to agree for a long rest (and that no one can be in combat) was already in place, anyway. So it's not like that was going to make a big difference.
Sure, the length of the day (or night) may extend a bit even for the player that was in "real time all the time". But so what?
Sure, Tuco, but that just sounds like making TB apply to all players when one player enters TB, which I noted was an option, but that I don't think Larian want to do that.
I don't play MP myself, so I don't know what is/isn't cool in MP; but I got the impression from others that the way DOS2 implemented MP ( independent player time-streams ) was a major point of satisfaction for the game, which Larian are therefore reluctant to change.
I suppose a partial solution that doesn't completely destroy their existing co-op flexibility might be to have a D/N flip similar to BG2, where players are only "frozen" when they pesonally have run out of day or night, and must wait for the others to catch up with their time stream. It wouldn't be problem-free, but might be less restrictive than every player entering TB whenever one player does.
