It's the Spectrum version of last year's 'strategy game of the year' for the C64. The graphics are a bit flawed in this version; still, I suppose a nuclear airburst over a city isn't meant to look pretty.
This doesn't feel like a wargame at all. Marshals of France attack superior numbers with fractions of their own forces, march in the wrong direction, and generally behave in a manner which would get them all reduced to corporal, if that, in about five minutes.
Although the Infocom parser is as good as any you'll get, the more I play Infocom games, the more I discover that it isn't quite as clever as it's cracked up to be. Oh, and make sure you don't play this on the C64. Disk access on this machine is painfully slow!
