I think LA Agartha's profile has been on the rise, and now more than ever has a big "Rush Me" post-it stuck to the back of its head. Its early game is truly horrific.
I just tried them for the first time and faced an immediate hydra rush (no diplomatic messages returned), followed by extortion attempts/war threats from my 3 other neighbors. Diplomacy doesn't seem to be as effective as people consider LA Agartha a late game threat. Of course, I lack Zeldor's silver tongue
I expect nations that I don't even border will start sending me death threats. Hell, people not even in the game might start telling me to give them stuff.
