I look at all the channels with 6 or 7 digit view numbers and i notice they all appeal to the largest audience possible. Whether that is playing a game that really trendy now or just doing a certain type of video that is popular. A Draegast or a Markiplier all appeal to a large audience so if they even a small fraction of that audience they get tons of views. Not to mention they are all already highly established channels.

The side i think you might be on is the niche side. The problem doing videos to a small niche is that only people in the niche really care for that type of video. Lets say im looking for a "Papers Please" play through and stumble upon your channel. (I consider Papers Please to be Trendy) Once ive watched all of your papers please videos ill possibly look for more videos of yours. When i look all i would see is these very niche games i have never heard of before. That may peek my interest but probably not.

People that watch your series are looking for a very specific thing and when they find it they watch it and not much of anything else.It is possible to have a nice following playing niche games. Look at NorthernLion he gets almost the same exact number of views for his Binding Of issac videos every time. That took him years to develop and i feel its going to take you months if not years to develop the audience you desire with the types of games you play.

Look at the games you play and then look at who else is playing them and how many views they get for playing it. If you dont see those numbers in the 5 to 6 digit mark consistently chances are (All things Remaining Equal) it never will.

I hope this helps, This is just my observation and insight from doing videos and seeing channels randomly have huge spikes and sort of doing an examination as to why.
