I was able to play my friend's advance copy this last weekend and I've got to say, Nintendogs is fantastic. It's by far one of the most adorable things I've ever seen and it's extremely satisfying to play around with. The most attractive thing to me is, of course, the more game-like aspect of raising money to buy things for your puppy. However, I am also excited to see if it sparks up to be even half the phenomenon it was in Japan with it's "bark mode" here in the US.
"Bark mode" is like sleep mode, except that if you happen to pass by someone who also has their game on your dogs will meet and give each other presents containing text that you've put in previously. In Japan it was even being used as a way for guys to meet girls, as they would put their e-mail address and information in the message.
Unfortunately I won't be getting Nintendogs at release since I have yet to purchase a Nintendo DS. Is anyone excited for the release? Anyone got it reserved yet? Which dog are you starting out with?
