Well it is an ASL for Fun scenario that he is putting out there for us for free. As George says:
there are some projects that just don't quite fit the mould for a scenario or campaign game - be they too big for a scenario, too little for a campaign game, or need a special map made for a scenario. Sometimes I just brainstorm up an idea and then design something for my local group of ASL enthusiasts to enjoy. For the most part, these scenarios are played once or twice and then are pack up and stored away in a closet, never to see the light of day again.
There is no promise of balance or anything else except that he tried to be historically accurate. If you don't like it fine, but its an experiment that didn't cost you a dime. No reason to go off
