There is no Minecraft for the 3DS.
The 3DS comes with the stylus when it is first bought.
It depends on where you buy it from and if you are getting a hard or soft shell. I personally got a hard shell case for $100. A soft can cost about $60 or someplace in the teens depending on where you get it.

You can buy 3ds action replays on amazon and walmart. those are the only two places i know.
It has dsware (dsi games), but you cant buy wii games for the 3ds

For the 3DS, the 3D feature does not require 3D glasses to play so you do not need to buy 3D glasses.
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.
