Your world page looks nice, but really, it has nothing. Maybe check out x145's world? Or Retro? Just make something saying List Of Features- Baseball Field, Airport, etc. And maybe a description of each thing, but that isnt neccasary.
Ok now I know what do you mean exactly :D I´ve some good ideas how I make it but I haven´t time currently to make it first in the next days maybe first in the holidays(because I have many to learn) but when I have enough time I make a list of the biggest buildings ;).
