The various Humble Bundles have gained attention for offering PC games to support charity and indie developers, but the idea is spreading. The Little Big Bunch now offers a pay-what-you-want set of five PC titles to benefit GamesAid, a UK children's charity. Distribution is being handled by GetGames.
The default amount starts at $10 with a 50/50 split between the charity and developers, but you can give as much as $100 or as little as free, if you're cheap. The site notes that there will be a small processing fee as well. You can grab the games for yourself on the Little Big Bunch site.
GamesAid primarily helps UK-based children's charities, with some support given to foreign charities for education, housing, health, and social welfare. It spreads the wealth among various small or mid-sized causes.
