9. Disgaea Series

Nippon Ichi's classic turn based strategy series is well known for its humorous story and deep strategy, but man are these games long as well. Regardless of which title you pick you'll get a massive campaign, but the item world offers the true cherry on top of our lifespan cake. Offering hundreds of randomly generated levels for each item, the item world lets you clear out enemies inside items and equipment in order to power them up. It's far more addictive than it sounds and is quite capable of sheering off whole years of your free time.
