Same here i can't wait for my conversion kit to arrive. I hear nothing but good things about climate.
I also enjoy evolution with the flight expansion. I asked if they could be mixed toghter and it's possible but some cards and events have to be removed to keep the game balanced.
I wonder how that would play out, since it can get pretty dicey at times trying to keep a large-body avian fed. Can't wait to give it a shot!
