The longest I've ever played was for around 20 hours straight a day, for 4.5 days, because I was a teenage on spring break and needed to play a brand new game from start to finish in that week and had expected it to take 7 days. I don't play for very long anymore though, certainly not hours on end lol.

i think 10 hours. i don't really remember. I just remember my eyes hurting really bad, I had to close them (which was easy because they were starting to feel puffy/swollen). I think I was playing Runescape or Mother 3 lmao.

When I re-acquired Pokemon Ruby after it'd been stolen, I played for probably 36 hours straight just to get everything back and get back to where I was.... and ended up beating it >_>;
