Nintendogs sales... The most popular game ever?

[shams]

I enjoyed Nintendogs immensely, and played it solidly for a few months. i found it didn't have enough depth (collectible items, areas you could visit, house upgrades) and stopped playing it once I had completed most of the achievables in the game. I can only imagine how awesome an online sequel to this game would be. Online dog competitions, meeting other people/dogs online, etc. Maybe the Wii version. .... Note on sales - Nintendogs is "effectively" a pack-in title here in Australia, and has been for over a year. Partially explain the insane sales (buy a DS, get a free copy of Nintendogs...).
