Anyone can tell you that the franchise Halo is a ton of fun and super addicting... but isn't easy, especially when it comes to earning it's in-game achievements. Prime, however, has managed to capture all the achievements for every single game out there today. EVERY. SINGLE. ONE. It's insane what he's done over the years and the people he's met because of this feat. Just ask Cortana...she'll be happy to display Prime's Halo achievement record for you.
