I personally am torn on the idea of planetary landings, I mean I like Kerbal space program for this very aspect, getting a craft to another body in one peice, but when you get there you realize it is just a barren empty rock with random topography.
The Evochron space game has planet landings, but except for a fairly basic station/city on the surface, that describes the experience -- just random topography, no weather systems, nothing interesting on the surface. FD will need to do much better to sell what will probably be a fairly expensive DLC pack.
it sounds like it could be a great concept but it doesn't really lend to the space experience, even if they had a million developers i doubt they could make unique planet content spanning the entire galaxy if i'm optimistic about the idea i can see landing areas in the same number that there are orbital stations with maybe more or maybe less variety.
going down to a planet is only gunna be really cool if there is something down there to do or get. but don't let me sound like a pessimistic sour , I'll see what they can do with it and if it seems like it'll add some extra depth to the game then ill buy the expansion. if not ill simply be content with what is already there.
That's my view also. I'm not getting my hopes up, but they did a great job with modeling the look of star systems, so I'm interested to see what they'll come up with. Procedural generation will work for varied terrain, and if they can manage to model different weather systems to fly through, that could be fun. I want a landing that mimics the drop ship landing sequences in the Aliens movie, following a glide path through clouds, and my ship saying "We're in the pipe, five by five."
I'm not expecting big cities on the surface. It will probably be something like small surface outposts the size of current space stations, with similar landing pads and UI for interacting with the base. We may get that before a full "walking around on the surface" expansion, depending on what they're able to come up with for alien plant/animal life. That's going to be tricky; there is a fine line between plausible and cartoonish. I'd like to see alien animals, but I don't want it to look like something out of the Spore game.
