Let's face it, games are great in all, but as soon as you've beaten them they can get... dull. Some games try to have as much content as possible, or they use dlc to add more, but you just end up beating it. So to alleviate that, you set personal goals. Clear out a random bandit wave in the fastest way you can, get the highest bounty, or complete a level without touching the ground

Skyrim is a big one; I got three, one is a bit of a game too. The first one is to pickpocket every character in the game, including the clothes they are wearing. Second is to kill everyone (kind of a duh). I only allow myself to do these after I've beaten the game and every single side quest in it. Finally the last one is a time based game. How long can I go without using the ethereal shout with a horde of continuing growing enemies behind me. What I do is I run around aggravating hostile mobs and npc's to increase the mob and then just keep running with them behind me. Every other shout is acceptable accept ones that calm enemies, or make you invincible.
