The massive expansion Prophecy of Kings for Twilight Imperium 4. The galaxy becomes significantly larger with the addition of seven never-before-seen factions. Forty new system and hyperspace route tiles add new planets and obstacles to the map. Additionally, thanks to player components in two new colors, you can now play Twilight Imperium with up to eight players. A tremendous scope, but that's just a fraction of what can be found in this expansion.
