nice, but
man, its just a TOO friggin hard, no matter what i plan, i always loose on age 3 or 5. i mean, they come, and all the units destroy my tower, and i cant defend it! imean, better add a evolution choise in your weapons automatically when you change era. but still, add a cheaper selection of troops, and just add a liitle bit of setback in the attack, or defence, because in the end, it was imppossible to get a soldier for a good money. i suggest you just upgrade tjheir strengh and decreasing some other feature, like armor and so on. or maybe make them faster or weaker. and maybe with stronger attack but no armory. and vice versa, sir, because its ok. but it needs these adds in, or it will be hard to play.
anyway, i think its great. nuice idea and the scenario is tottaly good! nice game, keep it on dud
