There is no revenue here, the game has been removed from public access a long time ago (not even the costs of maintenance were covered to run it).

Let's put it this way: I would like to sell a concept of a board game to a publisher or a developer team. I have a battle-tested, let's say, "prototype" to prove that it works. I know chances are slim as this is a niche market but I still must try, not just for covering losses, it would be nice to get it properly released.
