7. Skyrim - Oblivion Walker
Skyrim is a huge game unsurprising. It also carries a pretty easy achievement list, albeit time consuming. In your quest for 1000gs, you'll explore 50 dungeons; make a ton of iron daggers; save the world about ten times; and finally start to explore the side quests. Oblivion Walker requires you to get fifteen Daedric Artifacts equipment empowered by the Daedric Gods of the Elder Scrolls world. Each usually comes as a reward for completing a certain quest; it's here where the fun lies. The Daedric quests tend to be the most enjoyable that Skyrim has to offer, especially the insanity of the Hangover ribbing quest. It will take some time but you'll find it rewarding.
