Honestly, it doesn't matter which game system or edition, whether D&D or Starfinder, I never use the default setting, nor the APs and adventures. I just need the Core rules, rules supplements, bestiaries - setting and adventures are my creations. I've never needed that kind of game support, I create that myself. And now as a third party publisher, I publish it too. I am definitely not a fan of the Pact World setting, but I don't need to be. As 3PP, that's hands-off, and I'm glad for it, as it's not a setting for me either. I've written and published a two-shot called Rogue's Run and getting your ship upgraded at the end, is a part of the module. The fact that I don't care for the 1st party setting is a non issue for me.Not sure how well Starfinder is doing but judging based on forum activity, PbP advertisments for Starfinder games and the changes in release schedule I don't think its all that successful.
Personally I am a fan of the concept of Starfinder but not its executions. The designers are still stuck in a fantasy mindset and have no clue how to incorporate SciFi elements into it which is why the adventure paths ship you off into unexplored wilderness where the PCs can dungeon crawl without having to worry about things like laws, ect.
From the rules side starship combat was a bust and it seems Paizo quietly tries to remove them with the newer APs not even having starships or just using them once or twice instead of them being a part of the group to be upgraded.
