Hi conurebleu! Welcome to NWR's forums!
I absolute LOVED Kid Icarus: Uprising. I don't play it anymore since so many newer games take up my time, along with more important things like real life, but I was addicted to the game for a good while. The controls took getting used to, and I'm glad I'm not left-handed, or my enjoyment would have been considerably less than it was. The game was written well, had terrific action, wonderful music, and SO MUCH CONTENT!
As for the AR cards, there wasn't really any way to collect them easily, so I pretty much gave up on doing so. I still have and admire the ones I have regardless.
