Could you build this?

No Recreating a live MMO as an offline game requires reverse-engineering its network protocol, game logic, and data formats. That is a large, specialized effort well beyond vibe coding.

What it would actually take: The stack would be a custom game server emulating the original protocol, a launcher, and patched client binaries. The hard parts are decoding the proprietary packet protocol and reproducing server-side game systems from client analysis, which needs reverse-engineering and game-server expertise plus a large amount of time.
