LT,
Don’s essays are probably still the best thing around, especially the points regarding dead zones and purchasing for the long term. They don’t address the new units - artillery and destroyers – and they don’t take account of the new defensive capabilities of tanks or the lower cost of carriers (16 vs. 18 in Classic) and fighters (10 vs. 12 in classic). They are also a little too biased against strategic bombing, in my opinion. Strategic bombing can be part of an overall strategy, just not your ONLY strategy. As for taking the changes into account, I would say:
1. Tanks are obviously a much better purchase in Revised, since they not only attack at “3” but also defend at “3”. A tank can thus be viewed as a defensive purchase as much as an offensive purchase. For example, I like Russia to have several tanks because, when it gets down to the defense of Russia, it helps to have those “3s” to roll on your defense.
2. Fighters are more affordable in Revised, but the change in price isn’t like to cause you to buy a lot more fighters since they are still twice as expensive as tanks. They are still great for defense, but now, so are tanks!
3. The new units probably won’t change your purchasing that much – I rarely buy destroyers (and seldom see others buy them) and artillery are something you buy when you can’t afford tanks or have an extra IPC you can’t do anything else with. Neither piece is a game-changer, although artillery do help improve the attacker’s odds in small-scale battles, which comes in handy.
4. By far and away, the most important change is to the transport capacity rules. In Classic, you could carry two infantry or ONE of anything else in a transport. In Revised, you can now carry one infantry and one of any other type of piece, which makes it MUCH easier to transport tanks to the front. In Classic, being only able to carry half as many tanks as infantry in a transport tilted thing heavily in favor of purchasing infantry. Sheer numbers would overwhelm the superior attack value of tanks (especially when tanks only defended at “2”). But in Revised, you get a better balance among the various pieces, which means you have more flexibility in your purchase options. The addition of the artillery unit, while not earth-shaking, does round out your purchase options nicely to where you can almost always purchase to ensure full transports.
That’s not quite an essay, but that should give you the idea from one who basically learned how to play the game from reading Don’s A&A essays many years ago. :-)
