What are the good games in that bundle? I have none of them. Guacamelee and Steamworld seem the most interesting.
Haven't played The Fall or Stealth Inc 2 yet but they've been getting good reviews I think. No idea about Moon Chronicles, it's a FPS on 3DS, port of the original DS game I think, but broken up into episodes.
Woah Dave sucks, the rest are pretty great IMO, Guacamelee and OlliOlli are the best of the bunch, and Might Switch Force is really good if you like speed running things.
It's worth noting that for SteamWorld and OlliOlli you get both a Wii U and 3DS Code. OlliOlli has crossbuy however and once you download it on Wii U, you should be able to download it on any 3DS's that are linked to that Wii U.
