If you're saying there are commonly-understood standards in the games industry -- a shared language, so to speak -- then, yes, I agree.
That's not objectivity though; it's consensus.
So, if you really believe what you're arguing to me here, you couldn't personally recognize anything as being a quality product, if you don't enjoy it on a personal level? Or you could, but despite your personal opinion being unfavorable in terms of whether or not it's right for you, you still wouldn't say your recommendation of it for others is based on any objective qualities you boiled down in your review?
I mean that's fair enough if that's your take, I suppose. I just view it differently. We wouldn't be able to understand what does or doesn't resonate with people if there weren't specific identifiers of various qualities to make us recognize that. Anyway, I'll leave it that here, because this discussion doesn't really have much to do with topic of the thread, but I'd be happy to continue it in PM form if you'd like.
