Well presented set of rules at a reasonable price.
Could be used to represent just about anything you wanted to, and probably more of a template to create something than a pre-packaged system (although some sample army lists are in the book)
Full rules for unit creation are included and the author is very active on the Yahoo group setup to support the rules.
The WWIII supplement is good (if badly named) and shows the versatility of the system.
The rules could use more examples but other than that grab a copy and tweak to whichever period / crazy idea takes your fancy.
