I just got this game for Christmas and despite owning Human Revolution on Wii U I never got around to play it. Is it essential to play Human Revolution first or will I be fine jumping right into MD? Thanks.
They have a short recap video at the start of the game. I don't think it's absolutely necessary to play HR but you will miss some connections to the first game like certain characters and events. I played HR but didn't really remember the story all that much because that game came out years ago. Still had a great time playing and understanding MD.
