FD keep developing the game and adding to it.
However, as FD keep developing, more and more people find a) FD are not going as fast as they want and b) they are not adding what they want.
Nothing FD can really do about this. With regards to (a) its doubtful FD can magic up more dev effort, they have budgets and plans and other IPs to develop. We might like more, but DB loves ED we can be sure of that, and is dedicating as many resources as he can realistically do. With regards to (b) this is just typical and normal in a developing game. We all have our wants and needs. Some of us accept that we don't always get what we want and that FD have never promised any of us anything specific in relation to development plans and timelines, while others get salty because the devs don't do what they want.
This is of course exabberated by there being a bit of an information drought at the moment. FD are not being forthcoming with what 2.4 is going to be about (although the suspicion is aliens) and no mention of 3.0 yet. I'm sure most of us would like more info about the future development plans, but hey, its coming sooner or later, and we know how the community reacts if FD say something then decide to change their plans.
So yeah, i'm just sitting back, playing the game, enjoying it, and waiting for news.
I think the people that annoy me the most are those who complain after FD add something, and say it gives them nothing, so they are stopping playing (yeah, right, i bet). Presumably they were enjoing the game before, so nothing has changed in terms of how they could play prior to that so they can still do what they did.... but for some reason the addition of Holo-me, ship names, or multicrew cause people to stop playing because they don't want those... bizarre in the extreme, and smacks of throwing the baby out with the bathwater.
