> other example Mangos is "Wow emualtor"
Do they call themselves an emulator? I'm seeing "a server" or "a reference implementation".

You're right, I just checked , MaNGOS calls itself "a server" now. They probably had the same realization at some point. Maybe I should update my README too and just call it "a modern Ultima Online server" instead!. Less baggage.

Just update repo and README from server emulator -> server !

While I have your attention - let me wish you good luck with your project! While I'm not an UO gamer (my MMORPG has been WoW - that's where I know Mangos from :P), I'm happy to see a .NET project - I think it's an underappreciated platform; for once, Microsoft made something very cool

Thank you! And yeah, as a fellow .NET developer I totally agree modern .NET is genuinely impressive. The jump from the old .NET Framework to what we have now with .NET 8/9/10 is massive. NativeAOT, source generators, the performance work the runtime team does every release — it's a great platform that doesn't always get the credit it deserves.

  And funny you mention Mangos — the WoW emulation scene was a huge inspiration for UO server development back in the day. Different game, same passion for reverse-engineering and rebuilding these worlds. The
  community-driven server scene is one of the best things about MMO gaming in general.

  Thanks for the kind words and good luck with your WoW adventures! :*!
