New Nintendo 2DS XL Black and Turquoise
*Compared to Nintendo 2DS systems
It is a great system. The only difference is the 3DS XL has the optional 2D or 3D graphics, while the 2DS XL only has the 2D graphics. They both play the same games. It all depends on if you like the 3D graphics enough to pay the extra amount. It comes down to preference. For me, I chose the 2D XL because the extra graphics option wasn't as appealing to me, and it's a lower price.
Yes it does; it can play all the DS games.
Game prices can vary, but generally speaking are less than $50. The games names are 3DS.
No, you would need to buy it or redownload it if you already bought the game with a previous nintendo network account.
Unless I'm misremembering, yes it does.
No, you can only play games with other 2DS and 3DS players. Mario Kart 7 and Mario Kart 8 can be played only with themselves, not with each other.
Yes because it can also play 3ds games
