A Planet of Mine Mastermine Edition is a cozy 4X game , with the feeling of infinite playability and strategy, designed either for casual or serious gamers, where you exploit the planets of a star system to build a civilization and conquer the universe! Tuesday Quest invites you to rediscover A Planet of Mine in this MasterMine Edition , featuring: loads of new content, a way more robust game engine, a revamped UI for a better ergonomy, more detailed VFX, new music and far more sounds, improved AI interactions, and poop (yes, you read that right). Choose among 20 different factions ranging from space pirate chickens to nuclear scientist elephants! Establish a colony in a randomly generated star system. Manage the collection and production of your resources and advance your technology by unlocking new buildings and science. Trade with other factions or go to war for system-wide domination! Plan your strategy wisely and stay focused: you may encounter surprising stuff… Controls have been carefully tailored for portable consoles like the Switch, Steam Deck, ROG Ally, and Lenovo Legion . Create your own game The Mastermine Edition offers you the ability to create your own universe. You can personalize the sun’s type, the number of planets and factions, the distance of your first planet to the sun, and the global size of your world. You can also add rules like a specific game mode, or a limited number of cycles. So much power is in your hands! Reproduce and share any game With great power comes great responsibility, so now that you can control the universe, it means that you can create the best strategy challenges! And the best part is that now, you can share any game with your friends. Each generated star system has a unique seed that allows it to be identically recreated on another profile. So, you can simply share the Game ID with anyone and play the exact same game. Dare to defy your friends with completely ridiculous or very complex systems, and explore infinite game strategies together! Discover loads of new content   You’ll meet the Cyclopians, the Bulbinions and the Nautilians among all the previous species! You’ll build new structures and develop new technologies on new planets and biomes! That’s a lot of good news, right? Play with multiple species You can start with a party of 1, 2 or 3 animals, mixing species the way you want. The first selected space weirdo will represent your faction in the command center. Go on a mission Our team tailored several missions to complete: from easy peasy to hardcore! We enjoyed creating them so we hope you’ll have fun too! Stay in command A central UI allows you to access various panels: contacting other factions, managing sciences and ascension levels, displaying the stellar map, game objectives and Pandipedia. Enemies have a brAIn We improved a lot AI interactions: others factions now feel like real gamers. They’ll be willing to trade abundant resources only, as any sane gamer would do, so you can’t use friendly interactions as an infinite resource provider. Sorry guys! AI can be driven by objectives and play profile. You choose to play the way you like it better, peacefully or more combatively. Be a proud warrior There are many ways to start a war with one or multiple factions, but in the previous version, war was a state of the stellar map, so to leave the map meant to leave the war. In the Mastermine Edition, you’ll have to find a strategy to end the war by annihilating your enemies or by signing a peace treaty. And if you’re more into cozy gaming, we also designed a peaceful mode: this way you can build your base without fearing to receive an ultimatum from other factions. Don’t worry, stay cozy! Meet the Khutulists Masterminers discovered a mysterious artifact: an extract from the hidden tomes of Pandipedia. Let’s read it: 'Where did they come from? What did they want? We ignore to know it... But what we do not ignore to know, is that they dominated the galaxy hundreds of thousands of years ago. How could such an advanced people disappear, poof, just like that? But... did they really disappear?” ABOUT THE TEAM A Planet of Mine Mastermine Edition is crafted by Tuesday Quest, a tiny Paris-based studio founded in 2011.
