Well that's not really fair, is it? It's not like I can mind control people. (That's R'lyeh's thing.) If I could, believe me, you'd have been under siege from every direction the moment you attacked me. It's possible people noted that it's turn 45 and you still only have 3 forts, and nearly all of your gem income gains appear to have been from stealing my land and Mother Oak.
Besides, diplomacy isn't everything. There are still quite a few major powers left. There are quite a few nations I'm sure are happily clamming their way to stardom, I'm sure, and judging by what I can see of Pythium's attack on Caelum they've been putting their mighty gem income to good use. (Jesus so many Harbingers.) Not to mention whatever Pangaea is doing!
Really, I think right now those two are the dominant powers. They've had plenty of space and time to put their plans into motion. If they go to war I imagine the winner of the game will be whichever one of them comes out on top, simply because those of us to the east are too busy embroiled in squabbling to do something about it.
On that note, I have to say I feel sorry for you, Burnt Pies. Dead last in province, fort, army size, and income, and third-to-last in gem income (what have you been doing, Scriptwolf?!
I feel really bad for Thtb right now as well), with one of the major powers barreling down on you. Ouch.
