I used to play Elite Dangerous back in the day, and I always hated interdiction, npc or otherwise. As the one interdicted, you always are disadvantaged, especially by players who usually outgun their targets thanks to the systems at play in the game (engineering). Star Citizen though, it feels like being interdicted advantages neither side, and it actually takes effort to plan it out because the way it works is like a bandit group setting up ambushes along popular trade routes.
I've only been interdicted by NPCs but I've so far liked it better than when it happened in Elite Dangerous. Plus it gets my blood pumping to dog fight in a Cutty Red haha.
