Im an older, flight sim enthusiast that rediscovered flight sims because of VR and I've read this whole thread .
For me the most interesting takeaway from this thread, and the official responses, ( also combined with about 3 years experience with DCS) is that what we are really talking about is less about the tech challenges being discussed here for multiplayer support and more about what the user base demands.
DCS has created a great sand box for a professional flight model with multiplayer functionality. The user base is pushing the product into a dynamic, multiplayer environment with some smart and creative ways to work around existing bottlenecks. Whether everyone likes this or not that is where the energy is.
The future is clear, PFM on larger servers with dynamic, third party content / mission creators.
(Reread that sentence above.)
If ED can truly support this direction in the way the community wants (we know there's tech limits but theres also community expertise, - real experts not armchair devs) that can help workaround limits and move this sim beyond what we know today.
To sum up, if ED can enhance MP servers, the user base will "Buy'em and fly 'em", if not, there's only so many grey-haired single players spending their retirement money on the next module and that can't be a road to growth.
It's a good problem to have. Nothing quite like creating a successful product and then have the user base begin to move and drive expectations. My hope is that ED rises to the occasion.
I've never been more excited to see the update coming this Friday.
