I played the original Elemental, and have been playing each version of the Beta.  I have to say things have really improved with each release, to the point now where it's becoming that classic "just one more turn" kind of game.  I like the RGP element of the game, and now focus much more on my leaders than my troops.  I like to try out different leader styles, e.g., melee only, summoner, critical hit specialist, with each new game.

I do have two suggestions. 

1) Please make it easier to select certain units from a city.  Having to use Ctrl-Click is a pain.  Can't you have a fly-out window that allows you to select/unselect each unit in a group?

2) I may have missed this. but in the city info screen, can you tell if your city is specializing in growth, research or military strength (i.e., the choice you make when it hits level 2), and which bonuses apply?  On some games, I have so many cities that I forget which ones were to be my specialized powers for those aspects of the game.
