One sitting showdowns

Lateley Ive had a habit of finishing games-completeley in one go. For example I finished a visualboy version of Alien hominid in a double period of I.T today at school but I have also finished a stack of other games in one go so what has everyone else clocked in one sitting.

Super Mario Bros "original"

Star Fox 64

Mass Effect - stayed up 2 days playing it, only stopped for potty and food breaks, dont care to do it again lol

I once spent 18 hours going through all 3 POP games and I almost had a seizure but it was worth it
