My doctor uses these for capturing patient data. They are still getting used to them, there is some finesse involved in not having your palm or forearm interfere with the pen, but this might not be an issue for some games...Is that what you're envisioning? Dd3 is learning to use the touchscreen on ds' old leapster. She's doing well but there are some hangups - very small coloring areas and the sort of 1/2 beat you have to wait for the pointer to be recognized sometimes throw her off. She really likes it though.
