I will put my hand up as one of those few players who wouldn't be upset if Planetary Landings don't happen. But I know they will, I am just dreading the backlash. What I see happening is that some will love it but the forums will be full of Commanders complaining that you can't do this or can't do that. Things like 'I want FPS combat, give me weapons', 'I want to have dogfights in canyons, but there are no Commanders there, this game sucks', 'All the planets look the same, I want variety', 'The physics is wrong, a type 9 shouldn't be able to fly in atmosphere, I demand a refund', - well you get my drift.
All of that is true; forum wars are inevitable whenever something new is introduced. It's either completely unnecessary, or not implemented well enough, with very few shades of grey in between. But FD are weathering (or ignoring!) those sorts of problems all the time.
The thing we have to remember is that planetary landings were a day one Kickstarter announcement. FD were savvy enough to realise that they wouldn't be able to do justice to SPL in the initial release, so they offered them as a future expansion for which some people paid a lot of money (at least £90) to effectively "pre-order." It was as close to a promise as it's possible to get without actually using the word, and money changed hands on the strength of it. We already saw the mess that resulted following
offlinegate, with people demanding refunds and FD having to backtrack on their initial choice not to award them. Planetary landings
have to be implemented in some shape or form, because the backlash if they don't will make every previous forumstorm pale in comparison.
For the cities, as we are in the future, humanity evolved so we now make better use of space and resources with a minimalist and ecologic concept of living. So people no longer overpopulate one small area and realises individuas need more space to avoid crisis.
So they spread out through universe in an misantropic era. It would justify small cities(less work, better fps) Also most of them live underground due to some magnetic solar problems or atomic mayhem.
I like the idea of underground cities, and given that we have mining lasers perhaps there's an argument in lore that it's easier to drill down than to excavate and build up. I still feel that political and corporate egos would demand the building of bigger and more elaborate structures in the age-old story of architectural -waggling, but perhaps those people would spend their trillions on space stations rather than skyscrapers.
(On a tangent, for me one of the more annoying things about CQC is the back-story that one of the arenas is a disused space elevator. Really? The greatest structural achievement mankind has ever built and there's only one of them in the whole galaxy? And it's now used solely for the 34th century equivalent of motorsport?)
