Not wishing to give Ubi any ideas to keep this franchise going, but I think they should branch out into fantasy/mythical creatures.
Something like Petz: Dragon or Petz: Griffin would at least be a change, even if it's not that refreshing. Maybe not Petz: Pegasus though because it looks like a horse and we have more than enough of them thank you.
Plus if you release it around the time of the next Harry Potter film, you get some overflow interest at the tills.
Jesus... I think all these Ubi releases I've been making myself play are starting to affect me... I'm starting to think like a cynical money-hungry games publisher.
