I have noticed a few similarities between Caput Mundi and the original:
1) when it is humid (so… most of the time) it smells like dog pee.
2) there is poo on the sidewalk (the beta version has mostly gotten rid of that bug. But not entirely).
3) the inhabitants are totally convinced of their central position in the universe.
4) many of the inhabitants still think smoking is a good idea.
Also, it is a wicked lie that people here walk fast. THEY DO NOT.
