Seriously? 20 hours to analyze Skyrim?
The autism is strong with this one.
This is basically Patrician's videos in a nutshell - he tries to cover
everything and for every positive and negative thing he says he tries to provide detail and explanations from multiple angles while showing it in practice as his videos also double for a (mostly) main quest playthrough. Sometimes he does "work streams" where he watches other video reviews and takes notes and a common theme (often with much shorter videos) is that the reviewer will proclaim something (e.g. combat is shit) and he'll stop and ask "ok, but why?", not in the sense that he disagrees with the reviewer but in the sense that the reviewer made a claim without explaining it.
TBH i'm a bit disappointed that he seems to be largely ignored by people here considering how much effort and detail he puts into his videos as it is the sort of obsession with mechanics, story, etc that drew me to RPG Codex in the first place back in the day.
Though that is mainly for his TES videos, i don't think he puts as much effort in the other videos he has posted. Though FWIW he had mentioned that since the Morrowind video, the other videos are more of sideprojects and his focus is on the large videos.
