Galactic Civilizations 3, Stardock’s gargantuan space 4X game, got another update this week, bolstering the base game with some of the Crusade expansion’s UI and design changes, along with general performance and balance tweaks.

Crusade lavished improvements upon Galactic Civilizations 3, and while you’ll still need to shell out for the expansion to see most of them, some important ones have been ported over to the base game.
