Into the 1880s as USA and thought I'd share some of my thoughts. The only shortage I noticed was liquor -- even at #3 in the world (and trying my damndest to encourage liquor) I'd often have to wait for a few days, even a couple of months, to build guards. Admittedly, I don't keep much of an eye on the economy, though. The shortage did seem to rectify itself in short order -- I suspect an unusual number of wars in the 1860s (ACW, UK-China, among others) drove demand up sky high. Speaking of the American Civil War, it was fantastic -- before this beta, I cut through the South like knife through butter in 90 days -- this version was much longer, and if the AI was just a touch smarter, it might have won. Like others have noticed, GPs tend to intervene a lot more -- I found it impossible to take Mexico in one war without the UK intervening. One thing I do find irritating (honestly, it's a great beta, and this is my one complaint) is my complete inability to make alliances with countries that aren't in my sphere. Because of this, I can't even attack Alaska (Russia and I had bad relations and Seward's Icebox failed -- a nice touch!) without France and UK intervening. It's like the entire world has joined a coalition to keep me from expanding.
I also noticed that my relations with GPs are plummeting, even when I don't DOW them (Russian Empire and France, for example). Do the influence options, like banning embassies, cause problems with relations?
The UK is #2 in the world, but has the biggest military score in the world -- once again, it chews through India and China like nobody's business.
Anyway, that's my two cents, and I am eager for the final patch. On the whole, great job Paradox!
