Wow! So in other words, you start with one AR Game, unlock five more by beating them, and then a seventh cube appears that flips the table and reveals a Shop where you can unlock
another eight AR features by spending coins (coins earned via the system's pedometer, a.k.a. walking around with the system).
So in other words:
Six AR Games (default, or unlock by playing):
+ Targets
+ Minigolf
+ Fishing
+ Graffiti
+ Mii Viewer
+ Star Viewer
Eight AR perks in AR Shop (use pedometer coins):
+ Targets 2
+ Minigolf 2
+ Clock
+ Globe
+ Fish Collection
+ Free Fish
+ Free Camera
+ Level Editor
Is this correct? Then you add the Mii Maker, Street Quest, Face Raiders, MP3 visualizer, the face blender (take pics of two people, merge together), etc, and you have a TON of content packed into the portable alone.
Add Pilotwings, Steel Diver and Pokemon Black to the equation, and if it weren't for MvC3 and maybe DKCR, my consoles would be getting mighty dusty.
