Okaaaay... Now this is weird.
I just tried to post, and all I got was a blank message box when I clicked submit... but the messages showed up...:?
Remember, managing a nation is it unique to the player. For example, while this guy might build up his economy in the beginning, I build up armies, and use existing ones to blitz territories, and catch nations off guard. It also really depends on the situation of a nation. For example with Prussia, you really don't have time to build an economy with 2 regions and a load of other nations surrounding you. Pretty much, "if it ain't broke, don't fix it". So if you already have a strategy that already works for you, that doesn't mean this guy's strategy is better. Of course, it's good to take the information he gives.
