Advanced Discovery Scanner makes Exploration less "fun"
I have to agree with this sentiment. I recently changed from Basic to Advanced with Surface Scanner, and set off to explore (where someone has gone before...).
Before the upgrade, exploring a system requires some skill and perception - I would make several high speed passes over the System, looking for any point of light which moved against the background of stars, periodically honking the scanner to see if there wasy anything in the vicinity. Finding an object "out there" felt like an achievement.
Now, for the past couple of weeks, I've just entered a system, honked the horn, and cruised towards each object in turn. I rarely get close enough to see the target, as I throttle back as soon as the scanner starts to avoid getting deep in the targets gravity well. My screen is just radial lines, and it feels like a chore rather than a game.
Someone said that its not compulsary to use an ADS. Unfortunately I don't agree - we are playing in the same universe, and there is a sense of competition between the players, even if they don't meet, for which we must use the best tools we can obtain.
So what would I prefer?
Assuming that the discovery scanners are passive devices (despite the honk), then the longer you are in a system, and the more you travel around, then the more likely it would be to discover objects. Each time you "honk" the scanner, while in the same system, the game could keep count of time-in-system (since first honk), and distance travelled (linear since last honk). All undiscovered objects then test their apparent luminosity (size, albino, radiance or illumination, and distance) against the cumulated time-distance and sensitivity of the Discovery Scanner, to determine if they become discovered.
So you would have to fly around a system for a while, with the best scanner you can afford, to maximise discovery; but you could not guarentee that you'd discovered everything.
Of course, this sort of change would require a "reset" of the game (from an exploration viewpoint), and so is very unlikely to occur.
Meanwhile I continue to spend many hours diligently exploring extending systems, knowing that the "Discovered By" tag has already gone to some dude who jumped into the system, honked his horn, and jumped out...
