New World cannot be preserved like other MMO's
I'm not trying to stop anybody from attempting to but I want to explain something really quickly because I see people talk about the "legacy" project, even in game. People are saying it's like WOW or SWTOR, but New World is incredibly more complicated and for those unaware I understand why.
When WoW private servers were built, reverse engineers sniffed packets between the client and server, figured out what the server was supposed to respond with, and then wrote software to mimic those responses. The server-side logic, most combat, AI, databases etc. ran on a single executable (or a handful of them) that you could run on your own hardware.
SWGEmu benefited from leaked Sony documentation. City of Heroes was rebuilt by people who worked on the game and secretly ran servers for years before NCSoft licensed them. Even ArcheAge, which people point to as a success story, ran on conventional server software. For the most part you can just consider these traditional game servers, like one you could spin up for many source games.
New World's backend isn't a server you can run. It's a constellation of AWS managed services wired together. Per their own public documentation:
AWS Lambda handling 150 million invocations per minute for characters, guilds, sessions, achievements, queues, and contracts. Amazon Kinesis ingesting 23 million game events every single minute. API Gateway handling 200+ million calls. S3 for storage. Athena for analytics. EC2 hub instances for the world split across a grid but stateless, meaning they're disposable because all real data lives in external managed services.
None of this is a server binary. It's a distributed cloud architecture that requires AWS (or a full clone of all those services) to function. To replicate it, you wouldn't just write a game server emulator you'd have to build the equivalent of AWS Lambda, Kinesis, and API Gateway yourself, and then wire them together exactly the way Amazon did, without any of the source code.
Packet sniffing can tell you what the client sends and receives. It cannot tell you how the server computed those responses when the computation was spread across a dozen different managed cloud services, none of which you can inspect.
Unless I'm missing something preserving this game, or even getting it to load into the map from a private server and being able to interact with the game in a solo environment is next to impossible with Amazons help or some massive leak.
tldr; Amazon built New World as an AWS showcase and because of that it is practically impossible to preserve
