Other videos are not that successful, and the total view count of all the videos I uploaded in the last two years is only around 15 000, and that number would be much, much lower if Bloodcrafter wasn't attracting so much attention to the channel.
Since the most popular videos are based on Minecraft, Serious Sam and Quake, and with so many views in the period of over 5 years, the channel statistics are worth looking at to see some trends. I think it would make sense to say that the viewer demographics represent the actual player base.
The most significant change in the last 5 years is how Minecraft has become more popular among female players. In the first year(2011-2012) only 5 percent of players were female, and the data from last year (2015-2016) shows it is currently at almost 40%.
The percentage of Serious Sam female viewers/players jumped from 5% to around 16%. Quake 2 continues to be a "man's" game, probably because 90s girls weren't interested in it, and new generations don't even know about it, since the series is dead since 2005. But, looking at Serious Sam, which is a similar game, the new entries don't help much. Serious Sam continues to be most popular in Eastern Europe.
Other videos share the same faith like Quake, it's such a sausage festival that YouTube doesn't even want to display the statistics and it shows an error. Since most of them are about video game development, and are shared on some game development and gaming forums, my conclusion would be that we wont see a rapid increase in the number of female game developers any time soon... unless it is forced.
Another sad statistic is Linux. I only have the data starting from January 2013, and they show only 1.3% of PC viewers are on Linux, and 1.8% use Mac. The stats from this blog are a bit more positive, where 5% of readers are on Linux, and 5% on Mac (but these are overall numbers, not just for PC).
