Should I do a gaming channel?

I personally watch CoD and minecraft games, but occasionally some zombie games. I haven't heard of some of the listed games. Also i started a gaming channel and getting views at the beginning can be challenging. Also you could stream on twitch. Well either way don't hesitate to start one.

Not if you don't have a quality audio setup, a good personality, proper editing skills, and stable game framerates at a high resolution.

You sound like the type of channel I watch.

Depends. Do you have the required professionalism? Will your video quality be good? Is your audio quality good? Is your personality good? Is your content relevant? There are many factors to consider here.
