Every planet doesn’t have every material you need for crafting everything. But a single solar system likely has most of it. There are key elements on every planet that are meant to make sure a player never gets stranded. I guess one could argue for that to be a game mode though if it isn’t already where you very well could end up on a planet and have no way to survive.
A lot of people like the gameplay loop from day one but the initial lies about how multiplayer worked was a driving force behind the unhappiness. Once that was fixed it was a shallow experience but a lot of people would have been content with it. Instead Hello Games keeps supporting it and putting out new content updates. There are still a lot of features and improvements people would like for the game and those very well may see the light of day with the passion Hello Games has shown for improving it. That’s why so many people think favorably of them. There are a ton of other bigger studios that would never show this level of dedication and community support.
