The way I see it is this: A review has two primary purposes, right? One is to offer criticism that can enhance our understanding of a piece of art and give us an insightful, thorough assessment of its strengths and weaknesses. I think we can all agree that it'd be very tough if not impossible to write something like that after spending two days with a game.
The second purpose is to tell people whether or not a game is worth their time/money. I'd argue that review scores don't do a very good job of accomplishing that. They create the illusion of definitive, authoritative criticism, when really they're just arbitrary numbers that mean totally different things to different people. (A 7 at Game Informer, for example, is way different than a 7 at Edge.) To give a review score at all feels silly, but to give one to a game like this after just a few days seems unfair to your readers.
More and more I'm thinking that Destiny feels more akin to something like WoW or even Dota than it does to a traditional video game, and I question the value in providing some sort of definitive quantitative assessment (aka: review score) of a game that will be drastically different in months if not weeks. It's fair for reviewers to want to tell their readers what they think of the game, of course. But scores feel definitive and misleading right now.
I think that review scores are actively hurting video games -- for evidence of that, read this article:
http://kotaku.com/metacritic-matters-how-review-scores-hurt-video-games-472462218 -- and I sympathize with the level designers and artists and programmers who may have very well done stellar jobs, putting in countless hours every day just to ship the game, only to miss out on bonuses because someone cranked through the game in two days and decided it was "worth" a 6. I'm baffled and frustrated by the insistence on trying to give quantitative assessments to personal, subjective experiences.
There are rare cases when a game is "objectively" bad -- it's broken, it doesn't function properly, it doesn't do what it promised, etc. Aliens: Colonial Marines comes to mind. It's pretty easy to give that game a 1 and be done with it. But usually, video games deserve so much more than numbers. They really do.
