Earth 2150 is the sequel to Earth 2140 the use of nuclear weapons have pushed the earth out of its normal circulation around the sun. Earth is coming closer and closer to the sun. The whole climate changes. The three "states" left on earth (and moon) try to conquer the areas on earth, which contain the resources necessary to build a huge spaceship to escape from earth. The game has quite good 3D engine with realistic weather effects like fog, rain, thunderstorms etc. It features a huge amount of units; some can "dig" tunnels through mountains so that your units can drive through it. The physics engine is nice, too: if there is a crater somewhere and it starts to rain, the crater slowly fills with water.... When the sun goes down and it gets dark, all units and buildings have lights on them, which are really necessary.
