I am also not keen on the idea of “puppies in battle” but for an additional reason. In addition to the down side in terms of game strategy. I just don’t want to see these cute little guys fighting. But I realize I may not be speaking for the majority.
I love all the LDW games but I think I would like see virtual pets for Windows, - and I too would like to see a few more expressions, emotions, & behaviors. Also, if it is not asking for too much, I would like to be able to influence behavior more. So, for example, if I don’t reward the pet for shaking his foot, I could "train" him to stop doing it.
