This game is highly addicting!
Gameplay: Touch Screen and Voice has never worked better. You use the touch screen for scratching, playing, or picking up your dog's belongings. Talk allows you to give your dogs trick commands that feels like you have a real dog inside your DS. Even the minigames such as contests or washing your dog uses the touchscreen and voice well.
Graphics: Dogs are fantastic, Framerate's even better, items look well done, the only complaint here is that the backgrounds for Nintendogs is only O.K.
Sound: Barking, Growling, Music etc. are all perfect, it's just a shame that some of the music is a little repetitive. It's not to the point annoyance it's just something I wish was different.
Value: I can see my self playing Nintendogs for a LONG LONG time for many many hours a day. There are so many unlockables (toys, accessaries etc.) you can do anything to your dog you want.
Tilt: NIntendogs is extremely fun. The only reason I took of one from tilt is because I lose track of the time so much I've been late for a lot of things.
Bottom Line: Nintendogs is for any one who wants a dog, but doesn't want to clean up after it or anyone who loves dogs at all. Even people who loves cats will love Nintendogs.
