+Ship types are customized. Better check show for the details.
+.s1
+Dreadnoughts are more heavily armored. Frigates are more fragile.

+details. Non-mechanized units are slower and more vulnerable,
+artillery firing ranges differ, few units are light (but troop
+transports and landing ships can carry non-light units).

+Fortresses cost maintenance, like capitals.
+.s1
+Your refineries make less petrol from each barrel of oil than usual.

+Natural resources gold, oil and uran deplete much slower than usual.
+A 100% gold resource contains 2500d, a 100% oil resource contains
+2500o, and a 100% uranium resource contains 500u. Fully depleting a
+sector will take you several updates, and a small fraction of the
+resource contents will be lost.
+.s1
+Gold in mountains does not deplete at all.
+.s1
+Oil production does not depend on tech; you don't have to micro-manage
+to conserve oil.

+Breaking sanctuary constitutes a promise to play the game. Using more
+than one country is strictly prohibited.

+Server time is in UTC, which means there will be no daylight savings
+time.

+Everything you do in this game is logged by the deities for their own
+nefarious purposes. However, the logs are treated confidentially.
