It's the fastest selling Elemental related game yet. It's doing substantially better than FE which itself did pretty decently.
So then we get another expansion, right? 
The reviews are pretty spot-on, too. Except one little turd...
Frog, this game has consumed me. I think about it when I'm not around it. I can't wait to fire up another game when I'm done with my last. I'm a busy man and a new father, yet I've played for over 35 hours since release. I've been playing your games since Gal Civ 1 and have played every major release (not the Political Machine, but everything else you developed or published) and this is the best game you've made.
Not just that, but probably the best game I've played in the past five years. I will personally pay you $100 for another expansion. Please sign off on making this thing a classic. It's so, so, so close.
