Right. Even Yakuza, not played by anyone but Dan(Well, he played ONE of the games), worked because they were atleast paying attention to the game, and even despite that Alex was interested in it enough that he kept everyone on track.
MGScanlon and the Persona 4 playthrough are good because there is an interest in seeing where it goes by one or both parties. The apathy is only going to go so far for Kingdom Hearts. Especially since it does become an obtuse game, where if you're not paying attention in cutscenes, there's no quest markers to lead you to your next objective. Even in my multiple playthroughs of the game, there are some areas that are just so obtuse and easy to get lost in(Someone mentioned it earlier, but Whale is a good example of it. For me personally it's the Tarzan level.)
It'll be interesting, but the apathy...is kinda frustrating. Game Grumps for example, play alotta shitty games, but it's funny and it works. Like, they're doing a playthrough of Zeldas Adventure, and not only do they riff on the game, but even the frustration and apathy that the hosts display is played for laughs, and it's enjoyable to watch even a shitty game like Zeldas Adventure.
What I'm saying is that GBWest should take an improv class.
