Beat the last boss in Dragon Quest 9 yesterday. Total play time: 56 hours. I've played it off and on for the past 3 months.
According to the strategy guide, once you beat the game "You've just gotten started". They may be on to something, considering there are in-game awards for playing 100, 500, 750, and 1000+ hours. Not really planning on getting any of those...lol.
