This is a difficult subject. It’s extremely easy to fall into the trap of streaming popular games in order to chase those huge numbers. However, the unfortunate reality tends to be that you get lost in the very long list of other people that had that idea before you.
However, if the ‘popular game’ is one that you love, you shouldn’t let the fear of low numbers stop you from playing it. Your passion and enjoyment should show through above all. There’s no point forcing yourself to keep going back to a bizarre niche title because the directory has no-one else playing it.
