How will GTA V Online be remembered?

Did it start out clunky? Yes it did not start great, but think how many people were clamoring for this feature from the get go. Then the hype for the heists was what it was all about and after completing them all I could see why it took some time to make them. Post heists online was a bit of a lull, but from there I feel they began to hit their stride from CEO, Cunning Stunts, Bikers, Low Riders, Yachts, Import/Export, and now Gunrunning. I feel the first year and a half of online wasn't great, but looking back its crazy that we have gotten all of this content for free when things like CEO and Biker missions can have crazy payouts which allow to purchase items for the next add-on.
