I'll give you the ten keywords and let you be creative to come up with best titles for those keywords yourself. You can write interesting articles based on your view and concepts, however it makes suits you and makes the article look great. The keywords has to appear once in title, twice in description and 4 times in content with similar keywords to be around 2-3 times. It ain't very difficult if you like gaming niche marketing and are willing to put in your best, for a rather long term business relationship. These are not game reviews, though game related articles. So its comparatively easy. Thanks.
