How to win: make a city on very easy, get 5 people with 10 builder 10 soldier and 10 leadership and the best/most expensive gear you have, then go to whatever difficulty you want to win in... I think it's a pretty good mechanic that greatly encourages replayability.
*I got all three achievments in the first try...
either way, this is an incredibely fun, fastpaced, roleplaying/sports game that woul clearly deserve some more challenging tasks...
I think that there should be a save menu with the option of auto-save after finishing a level and a password system for people that do not play at their own computer or to help you if your computer crashes and do not want to start the campaign from scratch.
i think that another ending of the game would be the last stone head (the flying one guarding the exit) you shoot, shoot you back if you don't shoot it again in 5 second.
