The first game I played I enjoyed not at all. This was partly because I had no idea what I was doing and partly because I couldn't scroll with my mouse at the edge of the screen.
My second game I enjoyed a bit more--I began to get a handle on items, goals, and skills.
My third game was when the game started being really, genuinly, fun. I had a pretty solid handle on what I was supposed to be doing, and had gotten pretty used to scrolling with zoom/middle mouse button (although this is my biggest gripe with the game is not being able to scroll with my mouse at the edge).
Since then I've had 3-4 solid, fun games against the AI.
I've encountered only very minor bugs--occasionally things will freeze for a few seconds, sometimes I won't be able to see the stats of the items in the shops, once I had a ton of overlay text and it refused to disappear for a few minutes--nothing major at all.
Thoughts in improvements that need to be made:
-identifying demigods by team can be very, very difficult unless you mouse over them.
-it can be very hard to click on demigods. Rook is gigantic. I should be able to click on him midway up is body, not just at his feet.
-scrolling with the mouse at the edge of the screen *needs* to happen
-the graphics are beautiful, but it can be easy to lose things (especially instances of Regulus) in them. The smaller demigods should be more visually distinctive or it's very hard to see them unless you're zoomed in. (torchbearer is fine in this respect, rook obviously doesn't have this problem)
