They delivered the base game in reasonable order and have been iterating and adding content since then.
Whilst the early game was pretty sparse in terms of content, at least it was delivered and reasonably complete.
Star citizen abandoned its MVP (Squadron 42) awhile ago. That's why the combat sucks and there is still no core gameplay loop. A management fiasco that would be impressive to recover from.
Fortnite BR had very little beyond its core gameplay. There were few weapons and only a smattering of locations amidst a largely homogenous small island. But bit by bit, Epic added features, slowly, deliberately. They listened to their fans and made what they wanted as the game and the community progressed.
The result was one of the most successful, popular, and lucrative video games of all time.
Games should produce the base game they promised, and then just add expansion packs or additional levels (free to initial backers) to try and get everything else in until the money runs out.
Maybe even the old shareware style route of releasing Episode 1, 2 and 3 (although in the shareware days, Ep1 was free and 2/3 were commercial .. like 1 was a really long game demo).
