Did you ever spent an entire night playing video games, just to go to bed in the morning?
You know. Choose your favorite game and just pack hours and hours into the game, and even without realizing it, you've spent 6-8 hours playing through the night doing a majority of things in the video game.
I've done this plenty of times on Fallout 3, Skyrim, Assassin's Creed, Oblivion, Final Fantasy games....so on and so forth!
