-The interface is clear, and the tooltips help to understand things you can guess looking the icons. The tooltips give you a lot of information about your units and the enemy units in order to decide your attacks or movements, very good.
-Maybe the tutorial could be longer than now is, but if you 've got a manual, the combination by both can be enough to understand the whole mechanics of the game.
-As other testers have said, some messages pass too fast and can't read all the content.
-Playing the desert campaign, after ending some turns, appeared a turn report that was empty (the box was all white). What was supposed to contain?, the casualties list and the objectives conquered in that turn?.
-As mentioned in other posts, before buying new units would be useful to know the map where we'll play.
Except these minor issues, I haven't found bugs so far. Today I'll try to play some other campaigns and test the mp and the editor if I have time.
Regarding other posts that I've read talking about the speed of the animations or the use of the orders with the mouse, although the game could look like a RTS, is a turn based game. And you've got all the time in the world to think about your actions and tactics and to resolve a movement; and this is that I think is the best point of the game. Maybe I'm getting old, but I can't stand the stress of the "clik fest" games...
edit: I forgot to say something...when you zoom in with the mouse wheel, thre's no end. You can zoom into the terrain; maybe could be a maximum ponit of zoom.
