A little oddity this, flotsville. You don’t even sign up for it, you just enter where you want your city, and the name of it. Then as people visit it, it expands. A little like the Sims, obviously, except the only thing that promotes growth is vistors. Every visitor each day adds inhabitants and makes it grown. Have a look, have a go, and if you start your own city, let me know in the comments so I can come visit too.
