Does gaming affect sleep?

[Kasierith]

Any stimulatory activity immediately prior (30-60 mins) to sleep can cause difficulty falling asleep. Rapidly changing brightly lit images with mental concentration counts as this.

Holy shit, what kinda of magic is this? D:
Just launched it and my eyes instantly felt relief.

Thanks!

Yeah it´s nice, but you can´t use it when you´re working on pictures... so there´s that. ^^

A little bit. I stayed up until five in the morning this season a few times playing Diablo III.

But that's not really terrible as my shift doesn't begin until 2PM, so I can still get plenty of sleep.
