No it really REALLY doesn't. That's why their numbers have stagnated unless it's an "episodic" game like Wheel of Fortune. And even then that's only an additional 100-200k views at most. Hence, again, why they finally opened up a Patreon after years of railing against the mere notion of having one to convince themselves that the haters are wrong and that this is the "true golden age of Game Grumps."
And for anyone who doubts that, literally Arin's stated reason to do this playthrough was so those same "haters" would hate-watch it to bring in more views.
And it's not working.
Hell, less and less people are watching Mario RPG every day even despite that. It's why they ended up deciding to move down to one video a day, every day now. The main issue isn't the amount of videos a day or even the way the videos are numbered or marketed, although that certainly doesn't help matters: it's content overload, plain and simple. People are experiencing burnout from the show, but rather than improve the quality of the show itself, they just seem intent on chasing trends and reworking everything around it despite that. Because getting rid of the fluff and actually playing games they like is too much work.
