Ymir is a 4X multiplayer strategy game combined with a city builder where each player develops a civilization of pigmen starting at the stone age. It's an indie game produced and published by Thibaud Michaud in 2019.
The system requirements are taxing, and a gaming laptop with a modern graphics processing unit is obligatory for successfully running Ymir. GeForce RTX 3070 or better mobile GPU is required.
The RAM requirement of 4gb is easily covered.
These laptops meet the system requirements stated by the developer. Macbooks with M1 or M2 CPU may require Rosetta 2 to run the game.
