We guardians spend a lot of time in the tower, and alot of time defending the last city... it would be really cool if we could walk around the city we are protecting. Just for fluff like. Maybe if a fair with carnival games, see rich/poor areas of the city, refugees from war torn parts of earth...etc. I realize that this requires time from the art and level creation team, but it would really be nice to flush out the world and engage players, make us sympathize with the world we are guarding ;)
