Targaryen Dragons :
it would be nice if you could build more buildings than you have plots so each stadium would be different, would add another level of strategy to the game
Off course, and once you have filled every level up on every building, then you'll be bored and possibly retire due to boredom, maybe it would be nice if you can also do it like the google maps style, you can scroll around and you have another land on your left or right, kinda like that style...
