My vote is no, Because of a few things.
1. Average watchers want a commentator, nowdays, there is high quality content everywhere and you have to try to match it.
2. Title and tag your videos differently. You need to take a course/watch some videos on how to correctly title/tag/market your videos to gain the viewers your looking for.
For example, the amount of people who search: "Minecraft windows 10 diamonds!", is probably slim to none. While the amount of people who search "Minecraft Lets play", or "Minecraft Windows 10 Lets play", or Minecraft Survival, is way higher
