I played Fallout 4 and Tomb Raider for two weeks, finished the main story, mopped up most of the achievements and was satisfied and put them away. I played Halo 5 for a week, finished the story solo legendary, played some multiplayer and was very unsatisfied with it, and I put it away. Destiny is the kind of game that you can always play and find things to do. That's why I love it.
