And if a GOAT is a 10 and this falls short, does it only fall to 9? I'd say it depends on how it falls short, and if it is in one small way or many things. Thus, I think my 7.5 or 8 is perfectly fair to it. However...
This, and your other statements seem to show your difference of perspective. You're going by a single metric, that of personal satisfaction. This is perfectly fine, but it is important to see it is tied to it is how you received its jack of all trades style. Rather admiring it than always feeling like it is coming up a bit short of something else you have experienced, even if (as it does for me) that ends up being one of half a dozen other things depending on what part of the game it is, you admire the provided breadth of experiences as a whole.
I can look at it that way, and it certainly does more things at once at a higher level than most anything else that has tried to do many things at once, but I think my score gives due honor to that accomplishment while also representing the persistent nagging itch for it all to be just a bit better even if I've never seen such a package and can't figure how the design challenges would be fully overcome. I'm not sitting here deeply satisfied (9) or blown away (10) so I have to recognize what it is in balance with my feeling.
