Pictochat is almost exactly like IM, (Instant Messenger) except you don't need to get online, and you can type, write it our by hand, (with the stylus) or draw. You can chat, you can draw, you can tell stories, (each person takes a turn telling a new part in the story) you can even (sadly) talk to yourself. Any DS owner may join in: there are 4 chat rooms, each with 16 spaces for a chatter in them: that means that 64 people (within a certain range) can be in a chat room. I suppose it's possible for it to be impossible to get in a chat room at some point. That wouldn't be too fun! So there really isn't much to say about Pictochat because it's pretty easy to understand, not to mention explain. So if you are really interested in hearing about DS, go to the game sections.
