[SIZE=8pt]I think Bandai has the right idea by having so many characters in the Tamagotchi toys. It really makes playing rewarding and surprising. I think more games would be terrific, as would the option to raise multiple Tamas at once. A reward system could be set up. If excellent care, the individual could choose to raise two or three Tamas at once. Which would lead to choosing which Tama should be fed or played with at different times.[/SIZE]
I also think a watch Tama would be a neat and successful idea. I once purchased a Tamakaci Duck & Dino (you can still find them on eBay), and the Tamakaci was attached to a colorful wristband. As your Tama has to accompany you everywhere, what better place to have it then your wrist?
