You are welcome to hate the idea, but please come with counter arguments, not fallacys (like saying, no because they dont have exp, how did anyone get XP in the first play if not trying it out ?)
Again, you keep taking so much for granted. They get experience by hiring people with experience and then they let go of people that don't have that experience - which means that you potentially lose a source of institutional knowledge and experience on your bread and butter thing which made you successful.
So it's a huge risk in a market that doesn't really want more MMO's and which has a ridiculously high failure rate and then you are either bankrupt or you are in a position where you lost a bunch of your institutional knowledge...or both.
At this point I am *almost* convinced you may secretly be Ray Muzyka and you want to try to destroy Larian so you don't get shown up by their superior game-building skills over and over. Also because you are salty that WoTC rejected you for the BG3 nod. /s
Look - as it stands BG3 has some of the very best multiplayer I have ever seen, and there is nothing from stopping them (or anyone) from creating a mod that would allow multiple people to play at once up to whatever the server could handle within a persistent environment that is hosted. You would need a handful of modifications and a pretty powerful server depending on how many people you wanted to host - obviously you would need to build a custom module for whatever you wanted people to do (PvP, a Town with roleplaying events, a dynamic environment that uses Baldur's Gate as the jumping off point...etc...)
