Stellar Monarch: The Age of Technology

Summary pulled directly from Steam - Some text may only be applicable to Steam platform

ABOUT THE BASE GAME:

Stellar Monarch is a grand strategy 4X where you are an emperor not a logistics officer. It focuses on the grand scale of things with no micromanagement. There are rebels, assassins, court factions and disloyal admirals. In addition to traditional 4X mechanics you also deal with the internal affairs of the empire.

ABOUT THE EXPANSION:

The Age of Technology expansion focuses on technology and science. New optional research mechanics (random technologies, hidden technologies, additional technologies), terraforming mechanic, new alien races, astro engineers, construction of megastructures and a few minor additions.

There is an option to disable the expansion for people who prefer to play without it and an option to enable only some of the features of the expansion, so everyone can customize the gameplay to his/her own taste.
