A fabulously detailed game covering the entire ground and air war on the Russian front in WW2. The game is not for the faint hearted. I played the main campaign most days for most of a year until, after 162 turns, 70+ opposing units who were trapped in a pocket, simply disappeared. So on the one hand I got almost a year's fun, but on the other a game-breaking bug that means I can never complete the game. On balance, this is probably a win, but I'll give a negative rating so there is fair warning for others.
