Brightness: MAX

Symptoms: You’ve been waiting for months to play Gears of War 3. You told your girlfriend not to call you for eight days after the game release. The game is finally in your 360, and you're ready to jump in, but you can’t just yet. The brightness needs tweaking. The subtitles need to be turned on. Volume also needs to be adjusted a bit. And control sensitivity... that needs major adjustments. You do realize this is a problem that people in the 1600’s could never have imagined would exist, right? They were busy worrying about living past 10 years old and not getting mauled by a wolf on the way to the corn fields. 

IRL: Hell, we all know people who have similar rituals. Your dad, for instance. He has to say a prayer before every meal. Just don’t tell him it’s a "habit."
