I honestly don't know what a game can do to survive as a live service nowadays. Japanese live services games in particular are just DOA instantly, but even giants like Valve (Artifact) and Blizzard (OW2) are failing at this. Can't charge money upfront because no one would try the game. Can't go F2P with paid cosmetics/characters because people will complain about microtransactions (because these game companies are charities, right?). Can't change the game too much in updates, can't have too few updates. Seems like we are just going to be stuck with the same handful of old live service games for the rest of eternity.
