Yes, there is indeed a Humble Bundle in cooperation with Nintendo. But it's region-locked. Here is the list of countries where it's available:

Well, it is on Nintendo systems, you ever saw Nintendo giving their own games away for cheap even if it is for a good cause? (I guess they did but well^^)

You can really not complain about getting Guacamelee for $1 though... and the average price thing will get more games, maybe something good as well. 

Humble Bundle for Nintendo platforms?

Sweet!

Yeah I wrote that in my headline now. 

regionlocked...
A sad german over here.

noooo region locked... i would have bought it regardless of not owing a 3ds or WiiU right now..

Great deal! Although I've already purchased many of these :(

Guacamelee alone is worth the price of admission.

Sadly region locked, but I already have 4 of the games (and paid over 25€ for them during sales...)

Luckily I haven't bought any of these. So I got them all for $10.

Great value! I have Guacamelee and Steamworld Dig on my WiiU, but $10 is to get the rest I don't have still seems like an awesome deal.
