... SC on the other hand will remain a perpetual pre alpha demo for as longs as the backers are willing to fund it.
Well their income stream depends on this state of eternal development. CIG said that ship sales will stop once the game is launched which means that they have absolutely no incentive to ever finish the game. They must realise that they are not going to sell millions of copies of SC, surely most of the potential customer base have already bought in advance.
I don't really know why they need a constantly open money tap though, given that they said they had enough money to finish the game back at 20 million. And then they said the same again at 65 million - so they have had almost twice as much as they said they would ever need, but they still want more. Maybe they are just plain greedy.
As long as the faithful are willing to be milked regularly with these endless sales they will carry on.
Everything which can be monetised is, has been and will be. For example -
Forum access
Ships
jpeg concepts of possible future ships (IOUs)
cheap ships and concepts IOUs to use as LTI tokens
paint jobs (skins)
Weapons
Ammunition (come on Sandi this is a no-brainer)
Clothing (space shoe-shopping!)
In the future - space real estate, apartments and houses, space furniture, carpets, posters, lamps and other ornaments. Actually the last few are already purchasable for your (purchasable) hangar.
Repeating myself here to call the BDSSE - the Best Darn Shopping Simulator Ever
More time and effort seems to go into monetising, and the 'shopping experience' than ever goes into developing gameplay.
If and when the faithful get to the point of not buying any more, then whatever state the game is in will be declared the Minimum Viable Product (MVP) and CIG will shut up shop and go for a nice long cruise.
