I think this is due to a misunderstanding. It's not esports that attracts people to the game, but the game that attracts people to esports. If the game sucks but is focused on "e-sports" (DoW3), then nothing good will come of it. A good quality game attracts a diverse audience, including people who organize tournaments. So the main recipe for "e-sports" is a good, interesting game.
Thank you. Agree 100%
