I'll not talk about business, or cash-flow, other than to agree that to arrive at atmopshered planets, with Earth like Fauna / Flora, and Cities, well, its a LOT of work, and will require a constant stream of £££ to keep the devs in their coke and pizza + nifty cars
At the ED launch, I recall David Braben talking about multiple alient life forms being something he wanted in ED. People, even back then were talking a LOT about planetary landings, and hey, they delivered next year.
I'm pretty sure that Atmospheric landings is something DB wants, its just a case of delivering it, and doing it well enough. ED can then develop all the various aspects of what that means, as time moves on.
Where are we now?
We have planets, and we can land on them. They seem kind of sophisticated. There is (apparently) some kind of simulation of plate tectonics. This drives the placement of Mountains.
This Planet system is something I think Frontier must be proud of. Its not just Perlin noise mountains. Planets have actual character, with distinct features, canyons and what not.
Vulcanism is due soon, apparently, at least Geysers and Fumarols were displayed at Gamescom. Will we also see actual volcanoes? Super large ones, dorment ones, active, lava, spumes of methane ice etc. Maybe.
The next level is major atmospheres. I'm not talking thin and wispy, like Mars. But rather where pressure is high enough to produce winds, and where dust levels, and moisture provide high levels of distance haze.
High levels of moisture, leads to seas, and oceans. And they are fed by rivers. These may not be rivers of water. But you are still going to see bodies of liquids, and those liquids will come down in rain, and form streams rivers.
Such fluid flows leads to erosion. So now we see Planets where rocks are visibly modified and aged by fluid flow.
These thick atmospheres will have clouds. The seas and oceans will have bergs. In other locations, there might be comparatively high temps, and pools of boilings liquids.
And then we have life. How often? Well, unlike No Mans Sky, I don't think life will be very common. Apart from on Terra-formed worlds. At least there the life-forms can be transplanted from Earth.
But Alien life? Fauna, Flora. Heck, thats a crazy amount of work. So best left to last really?
We don't actually have any people models in ED yet, apart from faceless Commander models.
WHEN?
Im hoping, to see some of these elements come in, in future releases. Not necessarily in distinct Seasons, but rather, in phases, as the technology is "mastered"
And I don't expect each element to be nailed on the first attempt. Modelling things like Vulcanism, Weather, rivers, etc. Its complex.
WORTH IT?
Of course, come on.... you look down on those Earth likes, and the not so Earth likes, and you just itch to be able to fly down there and explore.
Truth is, many planets, at first, will be pretty barren. We might have to wait a couple of years before we actually can fly down onto an Alien nature reserve.
These planets offer a wealth of other game play, and just the fun of exploring VIABLE alien planets, with complex atmopsheres, rivers of fluids, volcanoes, and so on. Well, its VERY appealing to me.
