Blissing out over a mediocre game with some redeeming qualities is totally allowed. Most people do it from time to time (unless they're complete edgelords who hate everything on general principles while masturbating furiously to it.)
It's that he's such a manwhore about games. He can't tell the difference in facial animations between TOW and Bloodlines, or in writing between T:ToN and PS:T. That rather seriously undermines your credibility when saying anything related to quality.
mediocre? there's nothing to be ashamed of in loving crap. this is the codex, we all love some old, obscure, horrible turd somehow, and it's perfectly fine as long as it's aknowledged as a subjective taste. we love deeply flawed people, no issue in loving deeply flawed software.
the real problem arises when "this is the best thing ever since sliced bread", *then*, in that moment, you turn from a normal person into a total retard.
