I used it last year, shortly after my family gifting me a Wii. I tried to gather up all my previous registration codes from DS games and my new Wii titles, and just barely made it for the annual big gift based on reward status. I was glad I did, as the reward
was pretty nifty.
No chance of making it this year though, so saving my points for the next cycle. :( Also debating what to purchase with current points, but nothing in particular grabbing my attention.
Sorry that I didn't see your post before, but yeah... the cycle ends on the last day of June, so there is still time. Keep in mind that you get 50 points for Wii games & 30 points for DS games (I'm not too sure about 3DS games as the only 3DS game I have is SSFIV & it doesn't come with any points). Also if you register your consoles they are worth points as well. I registered 3 3DS's (my Dad's first one *which was defective*, his second one & mine).... needless to say, I got a shit load of points from those (120 a piece I believe).
