I've had to stop playing this. I always like the playing field to be even in my video games - because having fun is more important to me than overcoming the challenge. This doesn't mean I want to fight battles with the same number of troops on each side or something similar. I simply prefer that all players are subject to the same rules.
So in my game I have maybe ten provinces; Imagawa or somebody has 13-15 and voraciously taking any tract of land I can. Here I am, about to have the entire world come down on my neck because I raised the shogun's Ire, so what I want to do is stockpile. Build defenses for the coming storm. But I know in my heart the a.i. doesn't operate by the same rules and I know that Imagawa will take every bit of land without the Shogun declaring them enemies of Japan.
I really don't like that, that I'm subject to some crazy set of rules that limits how I play while the a.i. isn't. Other than that the game is fun, though I do miss the riflemen and varied artillery of Empire TW. I haven't even tried, at this point, to beat the campaign I started - I'm sure I could beat it or, at worst, run out of time (another rule I despise: the time limit), but I have a crippling fear of facing the rest of Japan. Because knowing from Empire and recon i nthis game, no matter how crippled a clan is; they could be hemorrhaging gold, the clan always has at least 15 units waiting to strike. Without the heavier fortifications of Empire (the cannons on the side of the fort) I don't feel comfortable fighting a war on like 10 different fronts.
Edit: Reading the comment before mine, Yeah, Shogun 2 isn't perfect. It is a really good strategy game, though, and likely the best of the genre has to offer in recent memory. My problem with the game isn't the little janky problems with it but the time period. The tiered forts are interesting, but ultimately, considering archers can fire into them quite effectively, very tiring. I don't like having mostly melee troops either, because they have to run through enemy fire to get the chance to be useful, and because ranged and melee units are seperate, unlike Empire (ignoring native Americans) I have to constant;y watch my archers to make sure they're okay. Watch them to make sure they're in range. Watch them to make sure they're not hitting my melee. Man, I just really miss artillery. I miss teh carcass shot and the shotgun shot... shot.
