Because the system has already been discovered or partly discovered, steller cartographics has already updated your ship with very basic information of what's there. If you want detailed information, you need to pay for it or scan. They gotta make money some how.
If you go to a virgin unexplored system, there will be no planets in your system map after the honk.
The FSS scanner does not change its purpose. You want to more info on a specific planet that you can see in your system map, select it, move your ship so it's pointing at the planet, open the FSS and resolve.
Seems alright to me.
Nice head-canon - just a few issues with it:
1. UC pay ME when I hand in data for systems so if they want to 'make money' they should be giving out the full data, not limiting it.
2. If the ship's computer already has basic data about the system, why can't I view it without having to fly to the system?
3. If the System map knows there's an ELW at 120 Ls from the star, and the FSS knows there's a body 120 Ls from the star, why is it not capable of collating these two pieces of information?
4. How does the UC data get 65 kLy to my ship when someone hands in data back in the Bubble?
Obviously the answer to points 1, 2 and 4 is "It's a game". The answer to point 3 is that FDev slapped a cosmetic layer on top of the old mechanic, rather than creating a brand new, coherent system.
What's your rationalization for the invisible DSS behavior I described earlier in the thread?
