As Phantasy Star Zero's Christmas Day release (in Japan) draws closer, we're being taunted with more and more media. The newest video showcases the excellent Pictochat-style chat system, which comes across as a more flexible, expanded version of the Symbol Chat system from previous games.
As well as simply writing/drawing what you wish to say "live," you'll be able to save a bunch of preset sketches (because drawing stuff like this as a Rappy pecks your face off isn't practical), and simply tap a menu to bring them up. We don't know how many preset speech bubbles you can store in this way, but the player in this video has around twenty in his inventory, so ... at least that many. Also, if somebody sends you a drawing you really like, you can save it and pass it off as your own use it yourself!
