I may be an eternal sceptic, but is it just me who can't stop thinking this "charity" thing could only be some kind of way to evade taxes? I mean, it's a well know fact that companies donate to pay less taxes.
Look at the sales page for Civ 5 in Steam. It says money will be donated from the sales to some charities.
Steam Store Page said:
SOCIALLY RESPONSIBLE: 2K Games is donating a total of $250,000 to four education based charities, and users' choices will determine how the money is dispersed: simply select your choice from the pre-selected charities during the install process.
Charitable donations (in the U.S.) are a deduction, not a credit. So they reduce your tax exposure by reducing your income. So it isn't as cynical as it seems -- they will pay a little less in taxes, but they really are making less money, too.
