Thinking about what brings people to watch lets plays is one thing the might be an interesting starting point to analyse what interesting strategies for content could be used for instance:
Some years ago, in the time where the internet wasn't the powerful mighty entity is nowadays one of the few ways, one could get information about what were the best games and what made them worth buying were game related magazines and such.
As the internet grew some other media took a hit, since a lot of new competitors arose, in some extent there is a portion of the people that search for lets play videos are because they are willing to get the game but aren't sure its worth it so they look for those videos to see actual gameplay, since sometimes, trailers can be misleading.
That being said, there is also the portion of the public that look at lets players for the entertainment of the personality in the video, for instance myself, i love to watch lets plays while i am working, since i love games and well, cant play the game while i work so i watch and sometimes just hear the commentaries.
There a number os styles one could try to develop, and well probably develop its on, what i could say is, if you didn't found your unique way of developing your content, experiment like crazy, keep doing the content your subscribers enjoy but also invest a ton, i mean a ton of time in experimenting, reasearching etc, also learning skills in other areas might your ideas as well, for instance learning more about filmmaking, composition, animation, sound design, music well anything that could add value to your content, i mean you might have someone do those for you, but knowing more about them opens your mind for the possibilities and also improve your way of communicating others what you want.
PS: my grammar sucks lol
