I am not going to say destiny doesn't have areas that need to be fixed or that I am blind and think it's a perfect game. I have played for 300 hours and can admit I got my money's worth.
This is a persistent world and needs money to continue. most games like this use subscriptions to continue creating content.

Those games have new areas. Not areas where you enter from a different angle. They also have a sufficient amount of space to store items. While the subscription more than makes up the bulk of their worth, the base game doesn't cost near as much.
