Letting France produce is like a handicap system for axis and allies. If you are that good as the axis, you leave France to make the game challenging ;)
I tried a few ideas for OOB to use the Mech and Armor elsewhere, in-game outcomes varied from the plan that “looked good on paper” :)
The goal was to use the quick movers against Russia early on and grab France round 2, figuring that France is much closer to German Production than Moscow is…however, the first real attempt to capture failed, and it was down hill after that.
Another time I left France for round 2, they built a carrier landed their fighter on it and made knocking out the British fleet very hard as UK also built up the fleet…again, I was going Russia first and didn’t have a sea lion threat…as I was trying to think outside of the box.
Since I like to try many approaches, I can tell you from my experiences what is “obvious” to other players, France should be taken round 1. When left for Italy (OOB) steps can be taken to force Germany to grab it round 2. I will however continue to experiment in hopes of a Eureka moment that can shake up tournament play…(laments how the internet has served to educate axis players and prevent large shake ups)
In short, France should only be left intact as a courtesy for the unfortunate player stuck playing France as their only country.
*OOB stands for Out of box rules.
