Galactic Expansion was a board game played with a ten-sided die and tiles to represent territories purchased by the player. At least two players were required. The game involved "buying" resources such as spice mines, shipping lanes, and smuggler routes. It was played on a game board covered with hexagonal territories, which could be purchased by rolling certain numbers on the die. Some of the hexagons on the board represented planets; others might be stars, asteroid belts, or nebulae. At certain points in the game, rolling a seven allowed the procuration of a new resource and a five the ability to place a new shipping lane or smuggler route.
A few months after the Battle of Endor, Temmin Wexley played the game against a repurposed Imperial interrogator droid.
