I have 225 games in my Steam library, now most of those come from Humble Bundle, you name your own price, and get loads of games cheap. I'm cheap. I'm okay with that. The added bonus of buying from Humble Bundle is that you can send some or even all of the money that you spend to charity, which is awesome.
Humble Bundle has never worked with Nintendo before (that I know of) and right now if you buy the Humble Nindie Bundle, you can get $88 worth of games for Nintendo 3DS and Wii U for about $10 right now. You can pay less if you like but you'll get fewer games, as it should be.
So help charity and get some sweet indie games on your Nintendo devices, also show Nintendo that this is a good idea so they will keep doing stuff like this! You've got about 13 days remaining, and the longer you wait, the higher the average will get.
Unfortunately, if you don't live in North America, this does not work for you. Sorry.
