Witcher 3 comes to mind.
Development for Witcher 3 started in 2011, the game was released in 2015.
Star Citizen development also started in 2011, with a much larger budget.
CDPR already had experience as a team after making 2 games and with all due respect to them, TW3 is very tinny and simplistic compared to what SC is aiming at.
BTW, Cyberpunk is from 2012, still not out yet.
So what they should have done is made all the stretch goals as additional free extras and made a game that had most of what they said would be there and then added the stuff at a later date. What they're trying to do is have everything they said in the game at once. The sheer number of potential game-breaking bugs that could exist must be giving the testers nightmares. Aim high but release small.
They're doing exactly what you're saying, one small thing added after another. If the game would have been as simple as it was first pitched, then it would have been a Freelancer 2.0 and all the "extras" would have transformed it into a different game altogether - Star Citizen 2.
Talking about another PC exclusive - ArmA 3 (a studio already formed, with plenty of experience with Operation Flashpoint series and ArmA series up to the 3rd installment) and after 5 years since it's out, the engine is still kinda broken, with no plan to fixt it, with the game being an "ok" experience only if you play it in a specific way. ArmA3 started small - compared to ArmA 2, with limited assets, going Bethesda's way - let the community "build" their game by mods.
Each to his own, but I would rather see a game pushed further away with more features added than launching a game that's like all the other games out there, bar a thing or two. And yes, I've kinda lost excitement over it. When it's out it's out, my only "fear" would be for them to run out of money, because gameplay/experience wise, I think will be pretty sweet.
