We've seen our share of Humble Indie Bundles over the past year or two—independent developers who gather under the "Humble" brand and release a bunch of their games priced at whatever people want to pay.
The latest one, Humble Bundle #4, might be the best one yet—for any price you want, you can get Super Meat Boy, Bit. Trip Runner, Jamestown, Shank and Nightsky. Pay more than the average price (currently tracking at $4.61 on the Humble Bundle site), you get Cave Story + and Gratuitous Space Battles as well.
There's no shortage of gaming to be done this December, but these are all great games, for a great price. And not only will you be supporting indie devs, you'll have the option to give money to either the American Red Cross or Child's Play.
Check out their (endearingly cheesy and reference-laden) trailer above. It's funny, I was quoting that bit from The Rock all last weekend for some reason.
