That's not the joke. The grammar is the joke!
"How cities in Anteworld game should look like"
Don't you mean "WHAT cities in Anteworld should look like?" Perhaps "How cities in Anteworld should look?" =P
In either case I wholeheartedly agree. In every case possible cities should be overgrown shells of their former selves instead of being wiped off the map. Roads should be easy to import from current data, then given an otherwise unavailable "aged" texture to differentiate from player-made roads. It would also be cool if you could reclaim and re-purpose decrepit buildings.
