Here you will find a list of games that are being hosted there. Our game is called "Solar" (because it said the name Sol was too short). Games are listed in alphabetical order and you will find ours under the "Games waiting for pretenders". You can click on the name to see who has sent their pretender in so far.
Another note: Make sure that Conceptual Balance Mod 1.3 is active when you create your pretender.
