oK if you haven't played this web based game it's pretty amazing. I love strategy games. There are a few things though i would change. One is, i wish you can build more then one thing at a time. Maybe the more cities you own, the more buildings you can build. Second, i wish when you upgrade your compass from 1 to 2 it actually makes a difference, something you might notice. But none the less, it's an exciting game that you coordinate attacks with friends and take down other alliances. I enjoy it. :)
