In every game I’ve played of every pacific or global A&A variant I own (which is all of them), I find that for both my opponents and myself, by the mid-game, all islands have been effectively gutted of troops. Those land forces just seem to be too valuable elsewhere on the offense, capturing new territories and projecting power, to waste them on garrison duty. My (and my opponents’) philosophy has been that if you can’t kill or drive off their navy, the massive firepower that those navies can bring to bear will make a mockery of all but the most prohibitively large island garrisons.
Nonetheless, as I was watching my opponent (for the Nth time) send unescorted transports ahead of the fleet to pick up some of the ‘freebies’ I had left around ungaurded, I began to wonder if building up to ~4 infantry on every economically or strategically important island would be worth the cost by forcing the US navy to similarly devote more money to land unit production.
If it works, it would be a nice change of pace from my typical strategies. Plus it would be great aesthetically. I’m not one of those (you know who you are) who insists that the game match historical patterns, but I appreciate the accuracy of the simulation when the game mechanics encourage historical behaviors (inherently, not by brute force).
