Follow your skills in Gaming and upload contents that shows the Tips/Tricks/Walkthroughs of the above mentioned games that you play.

You can also record your Gameplay and add a Voice-over into the Video Clip by demonstrating the steps or tactics that you used while playing that particular game or a particular move in the game. This will indirectly attract users to your Channel who are gamers and finding it difficult to clear any specific game level, they would simply search on YouTube for this and might end-up viewing your Video.

Do name your YouTube Video Title properly by keeping in focus about the Keywords and the content in your Video. At the same time design a cool yet simple Thumbnail which represents the video instead of Misleading / Clickbait.

Hope that helps, cheers. 

PS: Have enough patience and upload contents in your YouTube Channel regularly, don't be disappointed if you don't get more views or subscribers in the initial phase and it would take some time.
