There are lots of people here into gaming. Check the #game, #games and #gaming tags. If you post good, original content then you have a chance to do well. Use images and videos (just post in a Youtube link) to get attention. Comment and vote on posts by others to build your following. If you make videos then mention Steemit. If people come here and vote on your posts then you will do better, although it takes a while to build enough Steem Power for your votes to have real influence. Good luck
