How are you planning to attract gamers to your "physical" place? Why should they be interested visiting this place? Will you allow them to earn money or something?
Depends on how we'd market it. But the incentives are money and fame. They'd get money from the bets and also the possibility to know new people and attract organizations we're going to work with (which means sponsorship and possibility to play in international leagues).
The eSports industry is underdeveloped from my point of view and there's a lot that can be done.
