I am looking for a team of like-minded people.

"City-scale" is a vague concept. What kind of city, with what population? Tournaments in "Heroes" or, say, in "KosinKa"? In general, it doesn't matter what city. Online tournaments are almost always on a larger scale, and the level of thoughtfulness and organization is correspondingly higher. Absolutely identical conditions for everyone – this is when everyone plays from the same starting save. Or do you need me to explain in detail how the hero's specialty affects the game? To a tournament organizer with decades of experience? In fact, anyone can run their own tournament with their own rules for everyone who wants to participate. But not everyone will want to participate in it. Ah, here's another question: where can I read about your previous tournaments? Because so far, all I've seen is a lot of fluff and no specifics.
