GamesRadar - It’s Independence Day on Thursday. If you’re one of our American readers, this means you get a free day to sit at home in your Stars and Stripes underwear playing games. You might set off some fireworks and wave a flag. If you’re one of our British readers, it’s business as usual. Keep calm, carry on and try to avoid over-using the keep calm and carry on slogan. No flags, no fireworks--dull, by comparison.
