Gotta say, I don't normally purchase most Paizo products, I have purchased the core(though this core book cost me 500 dollars xD), bestiary one, and the Advanced Players Guide. For pretty much everything else I use the SRD.
But with this, and the other Numeria items coming out, I am going to be throwing a LOT more money at Paizo (Buying physical copies for myself, and PDF copies for my friends).
I really hope they continue to make products like this and not go back to "standard" fantasy. I love settings that mix fantasy and science!
Thanks again for being awesome Paizo!
