Does Naughty Dog need to keep releasing The Last of Us DLC to get people to come back for TLOU2? Would people be more excited for Watch_Dogs 2 if Ubisoft was still releasing DLC for the first Watch_Dogs?
A full-fledged Destiny sequel with a sequel-sized marketing budget will pull people back in without a ton of effort.
That said, there's really no excuse for them not to have something to keep players engaged during downtime. The problem is that whatever they add people will burn through in under a month, then go back to complaining about not having any new content.
I don't disagree that a full fledged sequel with commensurate marketing budget would pull the a large number of lapsed players back in, and potentially enough new players to offset those who didn't.
That said, attempting to compare Destiny's long term plan to a TLOU2 multiplayer is silly, and WD is even worse.
At the end of the day, it's a math problem.
For TLOU2 multiplayer, it's a safe assumption that by the time it comes out, it would have been more expensive to keep producing new material to keep users engaged than it would be to do the necessary marketing to win an equivalent-or-greater number of users back. That's fine; and the model for how most multiplayer goes: it's a mode to play within the context of that game. There's no 10 year plan for TLOU multiplayer.
The WD example is worse because it's primarily a single player game. But to extend the "math problem" concept, I think it's academic that if they'd done DLC every 3 months between WD release and WD2 release, yes, they'd sell more copies of WD2, but that it would cost MORE to produce that DLC than it would be worth in retained users, and therefore a losing proposition.
For Destiny, it's totally different. I'm sure they assumed they wouldn't retain all the players between major versions, but I'd be astounded if the plan had been "well, we'll hemorrhage players 1/3 of the way through year 2, and just break the bank advertising when we do have something". It's just common sense that the goal has always been to retain the maximum number of players the cheapest way possible and use marketing dollars to get NEW users. The problem is that content plan has clearly jumped the rails. Given that context, it's a little mind boggling that they aren't doing more by way of communication to stem the bleeding that has to be happening.
So yeah; while they *can* buy users back when Destiny 2 comes out, that's the worst way to do it. In hindsight, I guess i could have added "... unless they offset it with significant additional marketing spend". I guess I thought that went without saying.
EDIT:
The vitriol comes from fans because Bungie told them point blank: get invested. "Buy action figures, read the lore, love your characters; we're in this for the long haul, guys. This is Star Wars. This is Lord of the Rings. This is what you've been waiting for. We're gonna keep Destiny alive and well for ten years of amazing adventures!". And the fans believed them, and got invested. And then Bungie released their contractually obligated DLCs, expansion pack. Having done the bare minimum, Bungie decided to add micro-transactions to keep the money rolling in, and then completely abandoned the game. Now they write weekly updates so horrendously disconnected from reality, that it calls into question the mental health of the individuals writing them. Fans aren't over-reacting. The media isn't drumming up a storm. Bungie has utterly and continuously failed to deliver with their $500,000,000 franchise. That's news.
While this is worded pretty harshly, I think the gist of it is what I mean about comparing Destiny to TLOU multiplayer, or any other multiplayer experience, really. Failing after 1.25 years on a 10 year promise is bad. Not acknowledging the failure is worse. Not communicating in a meaningful way at all is worse yet. I really do think they'd be immediately and largely forgiven if they'd just lay out what's happening, and what their plans are, then keeping that transparency up. I honestly believe the best thing for the franchise and 10 year plan would be delaying until mid-2017 releasing a current-gen-only Destiny 2, and fixing the toolset. Destiny 1's infrastructure is untenable, and not a foundation to build a 10 year franchise on.
