Dude, you are flat out just wrong. Much of NMS' development team was 6 people, it expanded to 15 when it shipped, the and company as of the end of 2020 is 26 people.
And yes, they have done more than elite by a large margin, and less time, ED came out in 2014, NMS came out in 2016. NMS has added multiplayer, basebuilding, underwater game mechanics, different vehicles, missions, community goals and had 3 graphics overhauls in 5 years. (I know I'm missing a lot.) But yes, they have done WAY more than Elite has from where they started to where they are now. Denying that is just delusional at this point. The very fact you acknowledge how hard they fell flat on their face, and then worked to fix the game means you KNOW this you just don't want to admit it.
As far as quality, again your metrics are nonsensical, saying that a game is better quality than another by how much space on a hard drive is like deciding the merits of a mission to the moon or mars by how much cheese there is to be found on them.
PS. And keep in mind I'm not attacking the developers of Elite themselves, they ARE a talented bunch, but it's the people managing them that sucks. The glassdoor reviews alone tell this tale.
