I imagine a great many people in the game look for the best trade routes and are not quite content with the games limited search functions.
How do I know this? Well the fact that the apps seem to be quite popular among the player base here and on reddit.
Yes reading about the thargoids is possible but I was thinking more about the research and discovery of the aliens that seems to require a doctorate in mathematics, an oscilloscope and a heavy dose of pro-plus to figure out even the most basic facts about the aliens.
No in game mechanics exist as far as im aware that allow research into them.
People do it if they like, no judgment, I myself don't (only use inara for logging purposes) and I feel like I have the tools to find what I need when trading is concerned. As a miner though, I have a hard time finding the systems I want as there is no way to find your desired planet type (ringed) - but galmap is perfectly fine at giving you enough information to find profitable routes. Only BGS logic and "economy" knowledge is required, but of course you can't beat
the best route finding tool. Finding "the best" anything was not thought out by Fdev, same thing as engineers. They just seemed to think, in a very naive way, that the majority of people would be satisfied with a
not-so-bad roll, but min maxing is at the heart of player culture. And I can't blame either, when your real life time is put into balance.
As of thargoids, the question is indeed harder. I feel I am the precise target audience for the way Fdev approaches story content - I really like the fact that I'm a nobody in the galaxy, and that some research people do the research I can't do. And after they publish discoveries, I just read
nature... I don't feel like I need to be involved in every discovery, but I get it can be pretty unsatisfying for a lot of people. I would advocate for a broader range of discovery tools - in game discovery tools.
