Scores under 7 for Destiny are too harsh.
Boring/repetitive content and weak story, but with that level of production grants you a 7 to me.
Underwhelming because of crazy high expectations shouldn't drive the score down in my opinion. Everybody should just keep their expectations on a realistic level.
It reminds me of people claiming that (vanilla) Diablo III sucked after having played 100-150 hours. Sure it's underwhelming, but come on, how many games gave you that much value?
I must have sunk about 25 hours into Destiny, and I'm begining to feel that I might be about done with it. But still, it gave me 25 hours of pretty good fun. Not many games this gen gave me that much. It's clearly not a 9 or 10, but 6? Come on.
The very same game, not from Bungie, not from Activision, would have reviewed better. Again, not game of the year, sure, but better than that.
