I think that response is more in relation to the concern that first footfall will be instant where as discovering systems requires you to return in the data. I think the OPs thinking along with the concept that first footfall is merely emotional brings a logic to the arguement that first foot fall tag is ok to be instant. Discovering systems and mapping data "just" requires you to scan from your ship, these go toward explorer ranking and bring monetary rewards. Reward on returning data makes sense in terms of gameplay. First footfall you have to land on a planet and walk about, this reduces the practicality of the task immensely, ie the OP brings up the idea that would anyone really perform foot fall on 20 odd planets and moons in a large system just get a full collection of tags? I think this also feeds into the rather forced concern of the console players being a few months behind.
If Neil Armstrong hadn't made it back we would still acknowledge he had first foot fall, but we would have lost the moon rock samples and other misison data.
(this is how far I got reading the thread and have no clue about posts after this)
From my point of view, first footfall will require much less data transition than planet discovery and mapping, as a lore reasoning.
If we can report crimes and remote multicrew in a hologram from LY´s away, recording a ship landing on a planet can´t be that much worse to handle.
Neither less, there will be a fleet carriers about few hundred LY´s away at worst to sell exploration data probably at all times, so I´m pretty sure losing a first discovery or mapping won´t be much of such an issue than before.
I also wanna repeat that any system with population will not get first footfall tags but except may from mix of our / NPC names, and also hope that if possible, to eliminate rest of console users unhappiness on this issue I recommend FD also handcrafting few other known unpopulated very well known systems with a planet(s) of some interest.
And alpha-/beta-phase progress will NOT transfer to launch of Odyssey, to make that also clear for all.
Anyway, rest assured, this PC player would be damned to do some kind of "Dante´s Hell", if I start doing 10-60 footfalls for ANY system per day or something, especially as there is no financial reward on it (like in first discovery and mapping at UC on station / carrier).
Guess I´m not narsistic enough. Or then too much as I don´t care about other pilot´s names on planets at all.
