Yeah, the max 4 player limit and no dedicated server thing, kind of makes me sad and longing for what could have been.

Dedicated servers, high player counts, persistent database plugins, these are all good things NWN had since roughly 2005 or so.
They largely contribute to why Neverwinter Nights 1 is still played actively in multiplayer today, almost 18 years past launch date.

Workshop mod support with Larian's editor and the above would bring a LOT of lasting value to BG3 but I fear it will not happen.
If someone knows a thread/site/poll/petition to make this visible to the dev team, do tell (as a post-launch feature is just fine also).

I will probably ONLY buy BG3 if the above is implemented, otherwise DOS2 will serve me just fine I think.
