Why do video games keep you up

Because they're exciting? Improv: it depends i guess, some games contain an addictive ellement to them or some people just want to get the most out of it like the xbox 360 for example, some achievements can contain something like "do something for so many hours" i remember playin super smach bros. melee on the gamecube, i was tryin to get mewtwo, i stayed on my gamecube for around 8 hours from about 6pm till 02:00am Improv: because you just want to go "one more level" or you want to see the end of the game.
