If you want to stand up for games and our right to play them, check out the Video Game Voters Network at http://videogamevoters.org/
Of course, it’s sponsored to some extent by the Entertainment Software Association, whose members stand to lose a lot of money if video games become strongly regulated, but this is a case of lobbying I can get behind!
Check out Yahtzee’s Zero Punctuation PSA about it. (Sadly enough, Zero Punctuation isn’t available for the iPad yet.)
