I dont think so. It is a combination that attracts lots of players and they are willing to tolerate a lot of BS because they have nowhere else to go. And I dont see that changing in foreseeable future.
The people that had "nowhere else to go" are playing No Man's Sky and Elite right now, as we speak. Star Citizen may become a huge deal at some unspecified point in the future when they finally manage to implement a minimum viable product with even half of the functionality that No Man's Sky has
right now, but SC is not there yet and is unlikely to ever get there.
And then comes the kicker:
Even if SC becomes a game worth playing, by the time it does, it will have spent so much time in early access-equivalent that anyone who ever wanted that game
will have bought in already. The expected long tail of users waiting to get in that CIG is banking on (or rather, that they would be banking on if they were a more normal company) isn't going to appear. There will be no giant bump in cash influx because people decide to hop in en masse when the game launches.
Over the past few months, we've seen that exact scenario play out with PUBG: The game is still hugely popular right now, but its popularity is nowhere near where it was earlier in the year. As much revenue as it brought in (and make no mistake, it is a fantastically profitable game), it has already peaked in terms of usercount, and its post-launch monetization strategy is just the stupidest, most pointless lootbox bull**** possible.
That, on a much smaller but much more pathetic scale, is the fate waiting for Star Citizen. To continue at the envisioned scale, SC needs a lot of longterm revenue, the sort of revenue WoW generates via subscriptions for example, and outside of switching to an F2P-like monetization scheme, I do not see that happen.
Because here's the other kicker: As far as I can tell, SC is currently buoyed by a handful of people willing and able to pump thousands into jpgs. These are the sort of whales that F2P games bank on having, but because SC isn't designed as an F2P game, they have little incentive to keep spending once the game is properly out. Paradoxically, CIG have backed themselves into a corner where releasing the game
is actively harmful to their business model, something that I think has never happened in the history of games.
