Getting so obsessed with a game that you forget to eat, sleep, or even remember your own name.

I forgot my birthday because I was trying to save my fortress from a flood.

I sat at my computer for 12 hours straight because I was building a giant wall.

I asked my mom if I was still alive and she said, 'You look like it.'
