Casual:
The casual session is aimed at players who only want to do PvP incidentally or in a very limited fashion.
5. Players may not guarantee, ally, or be guaranteed by more than 1 other player nation prior to 2300, 2 other prior to 2400, or 3 others prior to 2550. An alliance may not have more than 3 player nations prior to 2300, 4 player nations prior to 2400, or 5 player nations prior to 2550. This rule does not count for any player controlled subjects a player might have. Indirect involvement in wars (for instance threatening someone with an attack unless they don't engage in a war against human players) counts as an alliance for the player being helped and thus is only allowed if the player being helped does not exceed its human ally limit in this fashion.
6. Player nations that are AI-controlled (absent players) are open to attack once they miss three straight sessions, you can attack during that third session. If the AI attacks another player in his absence, they can demand up to 50% war score, but no more. If an AI playing for a human nation joins a war against a human player as a third party, up to 25% war score may be demanded from that country.
7. For PVP wars: Achieving an overall war score of 80% also means the losing side must automatically meet the demands of the winning side. Peace demands can not exceed 100% war score. People can't be forced to peace out separately in a PvP war, to avoid peace demands from being truly excessive. Similarly, don't circumvent the war score cap by declaring multiple wars as a single alliance. If you do this, the total demands can't be more than 100%. If non-aligned human players both attack another human player, this obviously does not apply.
8. The first session will have a global non-aggression pact between all players. If an AI allied to another player wants to declare upon a player nation during this session, the player nation allied to the AI must decline that declaration of war.
9. Researching Jump Drive and Synthoids is prohibited (i.e. the Unbidden and AI revolt crises cannot be caused by players). Of course there's still the Swarm crisis which happens randomly, or maybe the AI researches those tech.
