I don’t often play computer games - after a day in the office, sitting in front of a PC again just does not appeal – but when I do I usually reach for Close Combat 3 (Microsoft). This game started life as an Avalon Hill project to develop computer ASL, and after many years and several changes of management ended up as this superb realtime tactical game covering the Russian campaign. As if that’s not enough, have a look at www.closecombat.org where you can download (free) game mods that will transform CC3 into a game about the North Africa Campaign, the Pacific War, or even World War 1 or the Gulf War. Amazing! If you can find a copy of CC3, for about £10 you’re getting a computer wargame with the scope and detail of ASL.
