https://github.com/NixOS/nixpkgs/blob/master/pkgs/stdenv/generic/setup.sh#L948
this can do it nicely.

+      Empire is a simulation of a full-scale war between two emperors, the
+      computer and you. Naturally, there is only room for one, so the object of
+      the game is to destroy the other. The computer plays by the same rules
+      that you do. This game was ancestral to all later
+      expand/explore/exploit/exterminate games, including Civilization and
+      Master of Orion.
