Yeah for me, Destiny is a 10. When you can get 200+ hours out of a game, it's a great purchase.
I have at this point pretty much stopped playing it, but it lasted me a solid 3 months of playing, something very few games get.
You may have put 200 hours into it, but are you totally blind to some of the obvious faults with the game itself? It's a reviewer's job to look at things somewhat objectively. It's true that there's no such thing as a truly objective review, but a reviewer needs to look beyond their opinion and also analyze the game itself.
Let's say you were tasked with reviewing Destiny in the weeks after it came out.
It's a game that had, at most, about five hours of content, and that might be being generous. The missions also largely lacked any sort of variety. Basically every mission involved walking into a room and either killing everything or deploying Dinklebot and killing several waves of enemies. Boss fights tended to be more endurance-based than tactical, as the bosses are just enormous bullet-spongers. The game's story was absolute garbage, and there wass no way to access the lore in-game (still no idea how that got past QA). There was no match-making for the raid, meaning that, if you don't have five friends on a similar schedule, you were basically out of luck. The maps were large and pretty, but largely barren of anything fun to do aside from plug away at the same enemies over and over again. The multi-player was terribly unbalanced and there aren't enough interesting game modes to properly sustain it. The gameplay itself was horrendously repetitive due to the ho-hum level design and general lack of variety. The voice acting was lazy and the dialogue poorly-written (seeing how good Dinklage is in the Game of Thrones game only confirms this).
Now, you yourself admit that you became addicted to the gameplay loop despite the repetitiveness, but can you deny that the repetitiveness was there? It's a reviewer's job to find the flaws I listed above and write about them, not to simply say, "well, I got enough hours out of the game to justify a purchase." I just don't see any way someone could analytically reward Destiny a 10 out of 10 when there are so many glaring flaws with the game. Sure, some of you guys were able to look past those flaws and enjoy yourselves with the game (we all do that with different games), but that doesn't mean the flaws vanished.
I've put over a thousand hours into Team Fortress 2 and still play it weekly, but that doesn't mean I'm totally blind to issues with the game. There are less than when the game came out because Valve patches it almost weekly, but even now there are lingering things such as weapon imbalances that I would point out if I were writing a professional review. I overlook them because I love the game, but they don't disappear because of that.
The same people that gave a 200 hour of fun game a 76, gave glowing reviews to Dragon Age Inquisition, which might as well be called fetch quest.
I don't think someone who is rewarding Destiny with a 10 out of 10 should throw stones based on
another game being a fetch quest.
Inquisition, at the very least, has a coherent story and semi-varied gameplay to go along with all the fetching. I agree it was a little overrated, but it still only averaged an 85 on metacritic, so it clearly showed some flaws to reviewers at large.
Reviews are pretty much useless, unless your tastes match up perfectly with the reviewer, which is next to impossible.
That's why it's the job of the reader to read the reviews and decide for himself if he agrees with the writer's assessment. You're never going to agree with every reviewer, or even the same reviewers all the time. But if you read enough reviews and actually see what they have to say beyond a final score, you can often come to a reasonably informed decision on whether or not you'll like what a game is selling. It's not a flawless system, but pretending reviews are totally worthless is a little ridiculous.
Now, if you go to IGN (just an example) and simply look at what they scored a game, yeah, you're getting nothing from that review. But if you read the entire review, along with a few others, you can generally decide with solid accuracy whether or not a game is for you.
As an example, I only read one review (from Polygon) of Citizens of Earth and was pretty easily able to decide that it was the type of game I'd enjoy.
