So 3DS's are expensive and 2DS's are less so and there are games I want for the 3DS. If I understand correctly, I can play 3DS games on the 2DS? Does this negatively effect the gaming quality or something? What are the disadvantages to buying the 2DS instead of the 3DS other than losing the 3D aspect, which I really didn't care about in the first place? Are there games that rely on the 3DS aspect that would be made less-so by purchasing the 2DS?

Sorry for all the questions, but it is a big investment, so I want to make sure of these things before we decide if we want to purchase one or not.
