The heroes also seem a bit questionable. There are a lot of navigators, and even if you're lucky enough not to have one initially, it's still not a guarantee that you'll be able to get rid of it later. Although, maybe it's not such a big problem... But it leaves an unpleasant impression. ;)
However, all this doesn't diminish the merits of the city's creators. The project is simply magnificent. I'm just not entirely sure about the balance.
