Toy stores such as Toys "R" Us and Laugh and Learn sell 3DS games both at their physical locations as well as online. You can also find 3DS games at electronic stores such as Best Buy as well as at online shopping sites such as eBay.
You can access the 3DS store from the 3DS menu bar. Once you do that, you can purchase and download games from there.
You can either of course buy the from a retail store (Walmart, Gamestop, Best Buy, etc) or go to the built in eShop. From the eShop, scroll left to find the "Add Funds" button. Follow the steps, and you are ready to buy a game.
Gamestop (EB Games) sells 3DS at MSRP, which is as of October 2013, $169.99
Video games are always changing. One of the easiest ways to find information on purchasing new 3ds games is to visit a store like Gamestop. Their selection is quite good. In addition, one could visit a big-box store such as Best Buy.
You can find video games at a number of stores that you might not have imagined such as Walmart, Shoppers Drug Mart and grocery stores. Additionally, you will be able to find these games at "traditional" stores such as Best Buy, Future Shop, and video rental places
There are many places to buy 3ds games. The best places that I suggest to find these new and hard to find games are GameStop or Game X-Change. Also you can look in store or online at Wal-Mart, Best Buy and Target.
One can find a Nintendo 3DS and a Nintendo 3DS bundle on Amazon. Amazon sells Nintendo 3DS and Nintendo 3DS bundles on their website at a reasonably low price.
It has a store that you can buy games in, sort of like the app store but at the sane time alot different.It's called the Nintendo Eshop. You can buy old school games such as gameboy or Nes, or buy 3DS Eshop games.
Technically, you can't reserve the 3DS anywhere, if by "reserve" you mean "preorder," as the system is already out. However, you may be able to get any store that sells the 3DS to temporarily hold a system for you to pick it up later.
Unfortunately, it is not possible to obtain free Nintendo 3DS Games. However, Gamestop sells a variety of Nintendo 3DS games, and anybody can purchase them new or used. If purchased used, they are sold at a much cheaper price for a decent quality.
The 3DS has its own games that only work on that console because they're too advanced for the older ones. But it plays regular DS games too.
No, that'd mean the 3DS would be open to all manner of software piracy. The way to download games using it is over wi-fi, using the 3DS Store.
