Fantastic game. You can say that the pathfinding is clunky and that the graphics are dated but those screwdriver arrows flying over a hastily-constructed stone wall as enemy cavalry circles around your new stone mine is an image still stuck in my head all these years later. The campaign is fun - and often challenging - and multiplayer with friends is a blast, especially when you start to diversify your troops through a long game. Buy it, get your friends to buy it and then nuke their cavemen with cyber commandos.
