As @Quenten said, in the current version of the generator it is possible to specify the exact number of gates (=number of roads). To do it add the "gates" parameter to the url (of the non-itch version of MFCG), for example:
- http://fantasycities.watabou.ru/?gates=1 - 1 gate
- http://fantasycities.watabou.ru/?gates=2 - 2 gates
- http://fantasycities.watabou.ru/?gates=0 - no gates (and roads) at all!
