That's actually what surprises me. I did everything to make the tournament run smoothly: a good, small map, a prize pool, good PR, and I didn't even have to recruit players... but for some reason, people don't want to play.... It seems offline play is dead :(

The map is interesting! I think it's perfect for an offline tournament with a prize pool. If it's just for a cup, then it should be smaller in size.

And you're really wrong about offline play being dead. A lot of people still play, it's just not always easy to find those tournaments.
For example, I only found out about your tournament halfway through, and that was by chance... you just need to advertise the tournament more, and then there will be more people.

Although, look, there are already 6 saves, and it's not even evening yet )))

So, either advertise more, or extend the tournament duration by 2 months.
