It's pretty useless, but it's free
The games graphics are pretty poor considering that the only color you can use is black and there isn't anything to look at in this except for the writing in the messages sent to you.
The sound is bad as well. The only things heard is clicks and a brushing nose when writing. You hear the clicks when you recieve a message, send one, or when you click on a letter.
The value is the only good thing about the game because it it free because it comes on the DS already.
The Nintendo DS's Pictochat recieves a 5.8 out of 10 because it is free.
