Hello everyone!

It's been a few months since we released the free 1.6.3 update. We hope you are enjoying that update with its new features and improvements.

In the meantime, we've been listening to your feedback, so here's a smaller patch that adds some improvements and a few bug fixes.

Compatibility and finishing an ongoing game

Saves from version 1.6.3 should be 100% compatible with this new version, so you can proceed with your games normally.

However, if you want or need to finish your current game with the previous version (1.6.3), please go to the Steam client -> Games -> View Games Library -> Right-Click on Interstellar Space: Genesis -> Choose Betas tab -> Select the "old_version" branch. If you require an older version (1.6.2) choose the "old_version_2" branch. If you require an even older version (1.5.3) you can choose the "old_version_3" branch.

For the best experience, it is advisable that you start new games to enjoy the new features and improvements fully, and to not have bugs.

Thanks

Thanks a lot to everyone who has bought the game, and the expansions, and has been providing feedback! If you haven't bought the Natural Law expansion yet, please consider buying as it adds 2 very nice playable races to the game, that will have their own Evolution tree with the Evolving Empires expansion, among other features and music tracks. The Evolving Empires expansion adds two major new features: Evolutions and Minor Civilizations. It also includes 7 new leaders and 2 new music tracks.

If you have a few minutes to spare, and have been enjoying what we do, please leave us a review on Steam! ❤️

Have fun!
