In related news: GalCiv 3 alpha should go live on Steam on March 27th. Please note: it’s a closed alpha, reserved only for those who pre-ordered the Founder’s Edition of the game.
Release date: still unknown. Here’s an image of a negotiation with an ugly alien. Also, it might be worth mentioning that diplomacy will not be available in alpha, as it is a feature that will be added in later upgrades.
