Yeah but the frustration is because this game is HARD. The interface is very good and intuitive. Between tooltips and right-clicking for more info you have pretty much all you need at your fingertips.
As for the eggs that frustrated me too, but you need a building you don't get until a ways into the campaign (like Shard 20 or so) to use them... Just in case this still bugged you.
Heh yeah it irked me a lil, because why let you get something you can't use? =P
Ah well.
Yeah the game is quite hard, but sometimes I do get a lucky break and thoroughly waste the AI, but more often than not it's playing defensive and whittling them down little by little.
I figure I don't take enough risks, and that just gives the AI the chance to get the jump on me.
For a while I didn't realize the AI can't capture a province with an outpost if there's even a single unit in the garrison. Combine that with the AI seems to enjoy waiting the 4 to 8 turns to knock down the defenses (Again, even if it only has a single weak unit), and I can send my highly equipped sorcerer scout on a merry rampage in their territory capturing as much as I can on my way back to knock off their Hero.
Problem is they end up making a comeback real quick half the time but it's not usually too big of a deal unless I make a dumb move or let the Quick Combat send my troops on a suicide mission.
Ah yeah, and there are some provinces the AI refuses to touch most the game, even after I capture 'em. Luck?
Bah. Final thing that's been ticking me off, but the AI seems to love necromancy a ton - at least on Beginner. Five shards in a row and each of the AI's heroes are spamming Crossbowmen and necromantic magic. Bad luck? =P
