Topic: Don't allow stargates into a cluster until cluster has tech to open
Allowing top ranked players to open stargates into new clusters just ruins the game for the newer players in that cluster. Because of their tech advantage the high ranked players can totally control the new clusters. For example they can trivially crush any player who disagrees with them. And they can go around and hand out all of the good resource stations to their friends. They make it pointless to build defenses since the defenses are useless against someone 100x your size.
Stargates in new clusters should stay closed until someone in that cluster has the tech to open one. The fun in game design is competing against people of equal advantage in the game. Lots of people quit playing when a game isn't fun and having another player 100x your size playing dictator when you're the serf isn't fun. Keep these large players out of the new clusters until the new players have time to grow up.
