When you say "original pitch", do you mean kickstarter times? The "no loading screen" was not a thing then, right?
Original pitch had limited landing zones, where you would approach the planet and watch a cut scene of the landing then get out of your ship. So from space, it would look like a full planet, but you'd only be able to land at specific locations.
In space it was going to be a bit similar as well, with PoI locations which you'd jump between, a bit like one of the early concepts for how ED would work as well.
However, when they started adding the extra stretch goals, somewhere between 10-50 million, they added a stretch goal to add full planets. Let me look it up....
Ah ah! 41 million (ACCOMPLISHED!)
Procedural Generation R&D Team – This stretch goal will allocate funding for Cloud Imperium to develop procedural generation technology for future iterations of Star Citizen. Advanced procedural generation will be necessary for creating entire planets worth of exploration and development content. A special strike team of procedural generation-oriented developers will be assembled to make this technology a reality.
Note, this was a stretch goal for 1 million. That's how much CIG said they would require to do this. Full proc gen planets.
Now, to be fair, they don't say it will result in the creation of full planets, just the R&D and setting up the team to make it happen later.
But then, where are all the stretch goals to actually implement all this? Simply put, it was the same as all the other stretch goals, just throwing stuff out there and getting money based on the hype. Over 100 systems promised for a million dollars each (sometimes, some were pitched at requiring more money, others less), but nobody stopped to ask, hold on, where are you going to get the money to turn these PoI based systems into full landable systems?
Just look at how much stuff that is on the stretch goals that still isn't implemented or requires a lot more money to implement than CIG said it would. Not a single ounce of planning and estimating went into those stretch goals, and this is symptomatic of the project as a whole, CIG are still developing the game without a clean plan for delivery of what they have sold to backers.
