This has always been my problem when I try to review 'really great games' like your recent submission 'stick wars'... I thought I suggested all my ideas when I push the submit button when strangler came to my head... right afterwards. Its annoying as hell, and i may have to wait a few more years but what the heck.
I mentioned hero units with rpg elements, defense tower, siege weapons, traps and what not. The landscape randomize itself from rocky, smooth, valleys, mountains with pros and cons depending on the region. Fire arrows work well in dry areas but not in snow among other things....
I'm kinda tired having to wait for units to came from across 'the entire playing field' just to get to the other side. Small outpost scattered around the area can be captured to increase production rate as well as serve as entry points for newer units. Of course its a bit slower the farther it is from the home base.
Thats all. Check out my suggestion in your submission comments the read my full suggestions. Keep cranking em out more of em great games ok.

It would be cool to make your own campaign or survival mode or arena or something o_O
