How to gain youtube subscribers?

I made a gaming channel, and I tried everything. I made good quality videos like Fallout 3, Brutal Legend, Tomb Raider 2013, Minecraft; I also made funny commentaries, I made catchy titles, shared it with my friends, but it didn't work.

I need to find a way to gain subscribers fast and gain attention fast. What should I do?

Have a sexy girl, tell her to do stupid things.

Have a pet animal and do soemthing creative with it.

Growing takes time, whether it be internet, life, or anything!
