I would rather work for a company who's philosophy was to work really hard for 8 hours then go home. Having worked on video games for 15 years, I strongly believe that somebody working 12 hours a day is no more productive that a solid 8 hours.

When you are in the office 12 hours a day you just start goofing off, your personal email breaks become longer, you chit chat around the water cooler longer, you might even feel the need to take a nap.

Work hard, work fast, then go home to your family and loved ones to rest and enjoy the rest of your day.
