I wasn't ready for this at all. Look, 3D games are nice and all, but this system is tailor-made for old school 2D platformers with 3D effects. I was playing this demo, and the idea of a Mega Man or Mario or Metroid or hell, anything just like it are ideas that I want to see come to fruition sooner or later.
The size of the screen, the d-pad, the game design etc. was a serious blast to the past. I don't remember playing the demo for Mudds on my original 3DS, but if I did, it certainly did not leave the impact that playing it on the XL has.
The Mudds demo alone has justified my purchase already-- I now know that it was indeed a good idea.
