I have no idea what your tastes are, or what you might have already played, but heres what I would suggest for someone who just bought an Xbox One and had $100 to spend: Witcher 3-$59.99 Shovel Knight-$14.99 Ori and the Blind Forest-$19.99 Total-$94.97 That's 3 amazing games you can get under your budget. You can't get much better value.
