Heh, yeah I wasn't a big fan of marching my heavy infantry into a heavy poison environment which is why I avoided the army vs army scenario after our first engagement (very well deployed, BTW). I did have a plan to flood you with mechanical men in addition to iron dragons to take your capital, but that got..er...sidetracked.
I hate leaving people crippled - doing just enough raiding to keep them from getting on their feet but I kept getting attacked by new people!
Have to say though that was quite gratifying when I finally smushed a couple dozen of those damn sirussh...they were such a thorn in my side for so long. Very well played for your first game!
