I'm not an EST person, but I have always loved West Coast games. As a kid, it usually meant my parents were in bed and I could watch the game in peace. As an adult, it usually means my wife and kids are in bed and I can relax and watch the game in peace. Everything between 6-9pm is usually occupied with the kids in one way or another, so West Coast games are a good opportunity to sit back and watch a game when all the day's responsibilities have been finished.
