If your boyfriend is a gamer, chances are, he's already told you EXACTLY which game(s) he's hoping he's been good enough to get this year. If he hasn't, walk over to his stack of games, make sure none of these are in there, then buy away. These are almost certainly all the ones he's hoping to find under the tree.
1. Call of Duty: Black Ops III
Price: $39.99 at gamestop.com
This entire franchise has been huge - if he doesn't already have this latest installment, but he has some of the others, this game would be a great gift.
