Nintendo is trying to make those who purchased their 3DS before the price drop feel like their money was well spent by offering a suite of 20 free games. The first ten NES games were expected to be released tomorrow, but you can go ahead and download them all now. You simply need to enter the eShop, select "Settings/Other," scroll to "Your Downloads" and then click "redownload" next to each game. It's a little cumbersome, but hey... free games.
Here is a full list of the free games available today:
The Legend of Zelda
Super Mario Bros.
NES Open Tournament Golf
Donkey Kong Jr.
Zelda II: The Adventure of Link
Remember, you needed to grab a 3DS and log onto the eShop before the price was dropped in order to become an ambassador and be eligible for these free games. There will also be 10 free GameBoy Advance games released before the end of the year.
I've had a chance to play a few of these games, and they all work fine on the 3DS, and my kids are ecstatic about having a brand-new (to them) selection of games. Also be sure to download the ambassador certificate, which allows you to set up notifications for when the rest of the games become available. Enjoy!
