Animal Crossing also started as a N64 title (right?), so its a bit older than just 4 years.
A lot of these titles have roots in games that are 10 years old (or more). But I guess they still count as new franchises.
Some extra titles to add:
- Donkey Konga
- Luigis Mansion
- Mario Soccer(?)
- Warioware(?) - started on GBA, or GB?
Throw in new Wii upcoming titles (Health, music, etc.............) and that's a very significant list.
