The Secret World Private: Server

Funcom remains the active owner of the Secret World IP. Unlike "abandonware," TSW and SWL are still monetized through the Steam store and Funcom's own portal. Cease and Desist:

If you own the original The Secret World CD key (not SWL), you can still download the original client via Funcom’s legacy portal. You can play the entire story solo because the game dynamically scales. It is technically an MMO, but you never need a group for the main questline. This is functionally a private server for one person, though you will have an empty chat window. the secret world private server
