Simultaneous turn in a turn-based strategy game.

Regarding the monetization of the lobby. This is, of course, Baratorch's personal decision. But why not make a common lobby and make it paid for everyone, not just for SOD players? This would reduce the cost for the end-user and increase the likelihood that true SOD players will start playing HotA.

Yes, you are right.
But there are reasons why I won't make the HotA content paid,
and reasons why I won't make the SOD lobby free.

For SOD, the plan is as follows:
paid subscription for a month/year
The lobby will, of course, only work when playing through the lobby,
otherwise, why would anyone pay for something that has been available for decades through Hamachi?
And depending on the level of engagement in the first few months, I will either close the project,
or simply maintain/administer it as is,
or I will develop the project, invest time and effort, and implement new features.

How much will the subscription cost? It's very difficult to say at the moment.
in the range of 60 rubles - 600 rubles per month.
I will be able to say more precisely after the results of the test free period,
depending on how many active players there are.
I may conduct polls within the lobby itself.
