Hi Stewart,
Welcome aboard, and thank you.
I have watched Lets Plays for Pulsar, but have not seen their connection system.
As well as a server browser in-game we will have a Faction system. Basically Factions will be our Guilds, where you can create a Faction group on our website and recruit members. Players can search for open/recruiting factions based on criteria (timezone, activity level) and/or tags (role-playing, fun, pvp etc.). Factions will have a forum and a calendar.
In game you will be able to see the Factions which you are a member of, showing any upcoming calendar events, the members who are online, and the games/sessions they have active (when you host a game you can choose for it to be Private, Friends Only, Faction Only, or Public).
