Part 24: Update 3b: New Units
Ichthyosaurus is mainly noteworthy for being the fastest thing we've yet seen. Unfortunately, a 1-move advantage over Gyroptychius isn't enough for me to want to waste Gond's super valuable time building one.
Maiasaura are faster workers than Thecodontosaurus. Maiasaura are faster MOVERS than Thecodontosaurus. Time is money when it comes to improving terrain and building cities, and they save it in spades. Glory unto the Good Mother Lizard.
