As a newfag to Oney stuff (aside from seeing shit on Newgrounds ages ago) I've been enjoying a lot of the popular series and finally got to YIIK. Generally it's super funny, but it does feel like Chris himself is trying too hard to be nice to the game. There is absolutely fun to be had with the game (more accurately, watching it, because the actual gameplay is nightmarishly boring) but he'll go an entire episode bitching about how awful the game is then suddenly exclaim how much he loves it. The cutscenes are funny, sure, but more often they're just frustrating. It's especially bizarre how he mentions at one point that he's enjoyed it more than any Mario game since 64 or something like that when their Odyssey playthrough was spent entirely with him giddy and praising the game at every turn. The boys even fought over the controller a few times.
DD and Julian are generally more measured toward the game though, and while admitting that it has its merits, they generally dislike it overall. Hearing DD begrudgingly say "Uh, yeah, there's definitely something there" every time Chris says "I love this" or something is funny.
