I played a little COD Ghost the other day.

You should consider using the BATTLE(gaming content only) tag. It will reward you with BATTLE tokens in which you can stake to increase your BATTLE upvote or sell on the Steem-Engine exchange. They can also be used to purchase games from the dgamemarket.

I have 30,000 staked and you would have earned a 12-15* BATTLE upvote if you had used the tag.
