I think you have it backwards.
The reason you stayed up late (Or early in this case) is BECAUSE the game had you hooked.
My dad calls it "Tunnel-vision" and it can happen to me just about any time of the day. If I'm really into a game, either because of its art, story, or gameplay, my body will literally need no food, water, sleep, etc until I am satisfied; usually by beating the game.
Case and point, I had a roughly 17-hour marathon of Metal Gear Solid 4 two days ago, from starting the game, to finishing it, while watching every cutscene, etc. I didn't eat/drink/go to the bathroom, at all. I didn't even feel fatigue after the binge.
This also happened to me with Warhammer 40,000: Dawn of War, and World of Warcraft.
