Ymir is a 4X multiplayer strategy game with city builder elements. The game was developed and published by Thibaud Michaud on March 16th, 2019.

In Ymir, all players start to develop their own civilization of Pigmen, starting from the stone age. This title has two interfaces, a regional view, and a world map view. World titles match a specific procedurally generated isometric zone that can be explored, settled, and built on by anyone. These zones can contain resources such as animals, plants, or ores.

The game doesn't let you control the population and economy directly. Your people will breed, age, work, and buy things on their own, according to the simulation. The population is divided into social classes depending on their incomes, purchasing power, and revenues, the resource prices get based on supply and demand systems, as well as rarity and production costs. Instead of set in stone game rules, the game's simulator makes all variables and actions in-game interact and influence each other in unpredictable ways.

Real-time battles in Ymir aren't instanced and take place in cities. Forts can be defended with walls, gates, towers, battlements, and canals can be dug around them and filled with water. Thanks to an advanced Strategic-tool, players can design their defensive strategy in case of attack, as battles are controlled by the AI and can happen without the player being present at that moment.

There are two main game modes available in the game: Real-time mode and Persistent mode. The first one is a classic mode that is designed to be played alone or with a couple of friends with everyone being present at all times. The Persistent mode is more like an MMO where the game servers runs 24/7 and all actions take more time. This game mode is meant to last several weeks.

A complex simulation/strategy/city builder with a lot of depth, Ymir is a must buy for anyone that's looking for an enthralling and engaging game.
