All the hype over this almost got me tempted to buy one just for the free 20 games, but then I realized this is really only a good deal for those who would want to buy those at some point anyway. Most people either already have played these games or have them in other forms so it is not as tempting.
If you can get past the 20 free games deal, the price cut is still going to be there (if not lower by Christmas), and I'm sure there will be some bundle or gift card deals if these continue to not sell well. Not to mention a 3ds lite or something. I would rather get it bundled with one real 3ds game than 20 emulations.
