Heh welcome to Dominion Endgame
I hope in a patch or dom4 that they add more ways to automatise your orders...
I am having a lot of fun at the moment even with the impressive micromanagement, and thus wouldn't mind continuing for a while.
However I am aware that it won't be possible to finish this game before another 50 or 60 turns. This is why I prefer to stop here before everyone start looking for a sub or staling.
By the way, gems factory add too much to micromanagement and it is better to not use them on the next game. At turn 80 I have so many earth and astreal gems income that I cast a wizard tower each turn and wish for powers on my main scs.
