This does seem like it breaks the "Greece and Myth" genre too much. I agree with the posters upthread... there were so many other Greek gods to choose from; I'm not sure why dinosaurs seemed like the best option.
It does seem as though the theme has moved away from Greek mythology. Dinosaurs, really? There are plenty of mythical units from Greek mythological times which might be more appropriate
Also, I think I would be happier with the "meteor" feature if it killed a percentage of it's targets as opposed to all of them.
And, the fourth spell: Unkown?? Too much gray area. Maybe at least a random selection from a set, displayed, group of spells.
However, some new features and challenges are welcomed by me. Evolution brings change and keeps the players ever-searching for the perfect formula to defeat our enemies.
