So you may or may not have been aware I'm working on my own RPG system and stuff. tl;dr version is Outlaw Star/Star Wars fantasy in space stuff. Now I have my "The Force", Aether and its reality-altering shinanigans. The fluff here is that the common man can't use aether to any reasonable degree, but they've learned how to build machines/magic items which act as collective aether-manipulating devices. It's effectively an artificer's society, where magic items rule the day when it comes to augmenting yourself to superhuman abilities. Except a few select few (PCs) who are the Jedi of the world and use aether as well as the magic items others rely on naturally.
Anyway, aether was my excuse for FTL shinanigans as aether doesn't let you break physics so much as change them to make things happen when are sensible given the new physics (why yes, the strong atomic force is much weaker here than normal, ATOMIC FIREBALL!) and one of the things it can change is the "density of space", which translates into gravity effectively. For sublight things, it lets them swim through "thickened space" letting them use props and fans to fly around, and zoom about with wings like a plane. For FTL things it does an accubere-drive thing, where its throwing out expanding space behind it. That works well enough.
Then I started dealing with extraplanar things, since the world has that, and I realized someone would have plane shifted to and fro from the prime material to some other plane and back and used that as one of the more 40k style jump drives that teleport you instead of move you "slowly" through space. So I had that, and much like 40k its kind of a crapshoot that isn't terribly reliable.
The issue here is now I'm worried I have too many bits of fluff. I got magic and needing to explain why magic can't just teleport you from here to there. I got FTL accubere drives which technically run off magic items doing their thing. And then I got 40k style jump drives. Do you think this will be too much for players to bother with? Should I be minimizing, or embrace it (I did have an idea of McGuffian anchor points being super valuable, since they make the usually untrustworthy jump drives more reliable and thus a plot point people can fight over).
Just looking for opinions, general feels, and the like. Also, happy to answer any questions this might spawn.
