What they do not show in their promo material doesn't exist. So take a good look at what they show, because there's a high chance that this exactly is what you'll get. Their Ship models are insanely detailed, so there'll be a very limited (flyable/enterable) selection available. The same goes for planet and station environments, which will be pretty, functional and small.
The hate is strong with this one!
A huge portion of the ship lineup has already been modeled in detail and animated for the crytek engine, and you can explore them in your personal hangar
right now. That means you can run around in them as we speak, if you purchase them they appear in your hangar and you can do all the things with them in first person/third person. If my count is right that is I think 10 fully modeled ships with variants for many out of the current lineup of 25 or so player-piloted ships. Not bad. Mind you some of these ships will be half a kilometer and larger with fully modeled interiors and working parts, etc. It's a lot do to.
The rest are being worked on, and the ones that are 'in the hangar' but not yer flyable for multiplayer are in the pipe for the next few patches. The ships that are modeled but not in multiplayer are currently getting all the passes for 'damage states' and all the varieties of different pieces being blown apart. One of the other programming difficulties is basically mating the two 'instances' of the ship simultaneously: the first person experience in the ship, say getting out of the pilot seat and walking around, manning a turret or station, etc, and then the 'space' instance of that ship flying around.
Perhaps you could clarify a bit more on what you mean by a limited selection of flyable/enterable? You can of course contrast with how many ships in EVE are enterable/exitable in first person
The station and planet environments will probably be modular and be expanded/added as things are finished. Remember that the interiors of these ships are also doubling for FPS combat levels as well. You're probably right about them being a bit 'smaller' but more detailed.
I'm not expecting anything from them that they aren't talking about and showing WIP of along the way.
