Throwing more pennies of thought into the ring that will be more related to the general topic this time, I promise.
Anyway, from a gameplay perspective, I think these are great. Expanding upon an a new mechanic to give us rewards for exploration. Both refreshing general exploration and giving us more ways of traversing the galaxy. Personally, I look forward to learning, and finding hilarity in, the catapult system to see how far I can hurl myself across the sector and see what trouble I'll find myself in from wherever I land. I look forward to trying it out!
I also sat and pondered the lore question as to why the player would be the only one with these abilities and I think I have a semi-reasonable answer. It certainly isn't perfect but I think it holds water as a general theory. To lay it out: we can see that the major factions struggle to truly explore space on their own. We can see this through two major point. First, there are the numerous missions offered by the factions to the player in bars, contacts, and over the open comms. The last one shows that these exploration missions are meant to be open to everyone. NPCs and the player alike. Which is why they can just be removed at random. Second, when we go exploring, the factions that are out there are: independents, pirates, *REDACTED*, pathers, and bounties. In other words, the major factions of they Hegemony, Tri-Tachyon, the Persean League, and the Luddic Church vessels do not leave the core very often. There are a few exceptions, but they are few and far between. So what does this create? It builds a situation where there is only a group of captains who are willing/able to leave the core to conduct salvaging and exploration operations. This isn't inherently small, but it also isn't necessarily massive. As such, only this group of captains will have the chance to collect the hyperspace data to build up to these technologies. You, the player, are one of those captains. The other half of this point is survival. Our dear developers have created a universe that is full of danger. You can browse these forums and find plenty of players who have lost their ships to pirates, *REDACTED*, etc. And, of course, plenty of us also cruise the sector and wipe out plenty of fleets. As such, the collection of captains who would also live long enough to build sufficient hyperspace data to even create these hyperspace techs is likely small.
To bring it all together, we play in a deadly sector where the the major factions rely on independent contractors, like us, to explore the universe and that the captains who would even survive long enough to develop the tech is a subgroup of those contractors. As such, we, the player, would be one of the few, and maybe only, ones who could exploit the information that we acquire to create such fantastic abilities. Thank you for coming to my TED talk. Have a great day!
