So, I think the topic for online play will feel more comfortable in this section ;).

1. Click "Online Game". Choose a server or create a new one. That's it :).

Hello everyone, for online play (I have a licensed version), do I need to add players as friends or something like that?

1) I go to "Online Game" - "Join an Online Game" and no games are displayed.
2) I create one myself. A chat appears. How do I use the chat? Do I need to create my own channel?

Describe in detail how to create an online game? With screenshots if possible)))
