Actually, diamonds are one of the most common gems on Earth, and it's only valued above other gems due to one of the all-time best ad campaign in history by one of the early pioneers of diamond industry.
Moral of this little nugget of info? Someone needs to put up a sustained campaign of how great
Oceanlab's works are and spread the word.
More a case of supply, demand and quality as far as I can see. Top tier diamonds of the highest quality, suitable for jewellery, are rare and international businesses like De Beers hoard tonnes and tonnes of uncut diamonds, in vaults, deliberately, in order to avoid flooding the market and so keep the price for the gemstones artificially high. Industrial diamonds are a different matter of course.
(Shit! I'm rambling about diamonds again on the Summer's Gone thread. What a dick!)
You're dead right about publicising OceanLab's work. I extol it and promote it at every opportunity, for what it's worth, although I'm no influencer let alone influential hereabouts. (Or anywhere else for that matter!) I think it's still worth doing because I only stumbled upon Summer's Gone by accident after ranting, on another thread, about how pissed off and disappointed I was with the standard of VNs on this site and somebody casually recommended Summer's Gone to me probably to quieten me down. Sick to death with poorly done, crude, hideous and lurid fuckfests with piss poor characterisation, dialogue, drama, tension, plot and story, I had just about given up hope as far as adult VNs were concerned until I began SG, which changed everything for me as far as the adult genre was concerned, in the blink of an eye, forever. Rarely has any work of fiction gripped me so quickly and completely or transported me from the real world into an luminous imaginary landscape peopled with a cast of fascinating characters as different, diverse, puzzling, annoying, delightful, confusing, hateful, lovable, infuriating, beguiling — basically the whole kit and caboodle of complementary and contrary things on the broad spectrum of human all and everything — that constitute people in the workaday world.
Fantastic.
OceanLab VNs seem to be loved, universally, by pretty much everyone who has read and got into them and it is a matter of deep regret that only a relatively small number of aficionados, so far, currently support the developer financially via Patreon or Subscriber. Hopefully as the VNs reputation and audience continue to grow financial reward will expand in kind, commensurately, because if there's any developer anywhere who deserves pecuniary reward it's OceanLab.
