Skies of Arcadia: Legends. FIVE YEARS.
I bought it, played it for a few hours, but then stopped because I had to get up early in the morning (we were moving house the next day). Movers were crap, and a bunch of stuff got lost or broken. I forgot about the game in the move, didn't find it unpacking so my memory was not jogged, and five years later I found it in an old chest of jew gold random bits and bobs. That day, my life was changed forever. I played the game all day, from the bit where you first get to Sailor's Isle right the way until Yafutoma, and then my mum came in and told me I'd been on the thing for like 15 hours, and it was time to stop. Just then there was a cutscene and she happened to watch, just as the giant ship battle began. When she saw the ships shooting each other and all the people being killed, my mom got scared, and said, "You're movin' with your auntie and uncle in Bel-Air." I whistled for a cab and when it came near, the license plate said fresh and it had dice in the mirror. If anything I could say that this cab was rare, but I thought, "Nah, forget it. Yo, holmes to Bel-Air!" I pulled up to the house about 7 or 8 and I yelled to the cabbie, "Yo homes smell ya later!" Looked at my kingdom I was finally there, to sit on my throne as the prince of Bel-Air.
On straight play, I logged over 300 hours on Pokémon Ruby. That game rubbed me the right way...
