An interview with Satoshi Sakai, producer of Phantasy Star 0 for the Nintendo DS, was published in the latest issue of Nintendo Dream Japanese magazine. Here is a list of new game details revealed.

- Phantasy Star 0 is a completely new title set in a brand new world.
- Phantasy Star 0 's gameplay mechanics will be based heavily around PSO's. But despite this, the developers hope that the unique style will attract more fans to the series, even those who have never touched a previous Phantasy Star title.
- The Nintendo DS was selected as the platform for this title to help broaden the age range of players.
- 'Zero' was selected as part of the title to invoke thoughts of a new beginning for the series.
- You will be able to play with people you've never met over Nintendo Wi-Fi Connection. No details were given on if or how Friend Codes will be used, however.
- Phantasy Star 0 will not support voice chat or vibration functions.
- PSO's word select system is a possibility, but has not been confirmed.
- PSO's symbol chat will not return for this game. It is being replaced by visual chat, allowing users to draw their own pictures using the stylus.
- Many common item and technique names will return from PSO.
- The developers hope that, despite this game taking place in a completely new world, it will still bring out feelings of nostalgia and other fond memories.
