How a good business model makes a good esport game
StarCraft II will die as a professional esport due to an in-built, genetic flaw. Same as all esports before it. League of Legends might be the first game not to.
The game’s longevity lies in how well it manages to replace its leavers with fresh blood. I consider a game dead (or dying) when it ceases to deliver new champions and when more people leave the scene than enter it.
One would think that the life span of an esports title depends mainly the quality of its gameplay. That is not the case. At least as important, if not more so, is the business model behind the game.
