We don't have to tell you about the resounding success of Nintendogs -- it's likely that you've played it, or at least known someone caught up in the doings of their electronic pups. Dozens of knock-offs and other pet franchises are crowding in as well, hoping to cash in on the demand for portable pets. The DS does seem uniquely suited as a system to virtual pet games of all types; the touch screen, after all, offers a level of versatility most control schemes can't match. Convenience is another likely factor in the popularity of such games, and the DS is nothing if not convenient. The question is -- do you think any game can match Nintendogs when it comes to virtual pets? And what do you think of the genre in general?
