Your argument is flawed. Those games all come from an era that was extremely restricting. Hardware limitations, lack of Internet and a gaming industry still growing all influenced those games. At the time, it was fine for a game to be repetitive & a grind, simply because that was the norm. It's now 2015, none of those restrictions apply to Destiny. They have the finance & means to supplement this game continuously and to some extent, lessen the grind… not eradicate it, but bring it to a reasonable level. Instead, they use grinding to extend the game as opposed to supplementing it with actual content. So your comparison is null.
