150 dungeons that take an hour to explore, along with 240 houses (above ground places) that take half an hour to explore, 10 hour sidequests, 20 hour main quest.
Well i was just trying to get to 300 hours that was all.
They are probably calculating exploring the entire map and participating in all of the jobs and crafting available. There is more to the game then just questing and dungeon crawling.
