A few years ago I was supporting quite a few devs. But back then, most games were updated monthly or bi-monthly and I could keep track of what was going on without having to dig through discords and the like.
Now I'm only supporting a few, that I really like / trust in.
Back then, if a dev was reliable and consistent, with a few exceptions, a game could be completed in a year or two.
I understand hardware got better and everyone wants their visuals to look the best - but if an update takes 6-12 months, a game with 10 updates, means an investment of 60-120 months until it's done.
Even with the most reliable person in the world - who can say what will happen in the next 5-10 years, good or bad.
This is why I don't see an end for WMV in the future. After 5 years look at where the game is at. Would anyone say the story seems to be at a halfway point? Not even remotely close. How many years will it take to get to some semblance of completion?
I think as others have repeatedly stated, at this point WMV is a money faucet. There is absolutely no incentive for BD to ever complete the game. If he did, what are the odds of him having a second successful game to support his new lifestyle?
The sad reality is the early "golden age" of western AVNs has passed. All the spare time people had while cooped up at home due to a global pandemic is over, and now people who want to make a game as a "hobby" have to balance life/work/development a lot more. So "hobby" games come out in slow trickles.
The next group of devs are the wannabe "professionals", who make a game, do an update or two, and then drop it and start again (often under a different name) if the first, second, whatever try wasn't an instant money maker. Sadly some of these games are really promising, but never to be updated, let alone completed.
Then there are the milkers. Devs who make a game, get an audience, and then ghost it while still collecting their Patreon deposits, or do an update every blue moon to make the game still feel like it's under development. Part of this group are the perpetual "Re-work/remake" crowd, who re-do the same content multiple times, or stop further development of an almost finished game to go back to the beginning. This group has grown a lot since AVNs took off on Steam, a source of income for recycled AVNs.
If you had to guess which category BD belongs to, what would it be? Funny enough he considers himself alternatively a hobbyist or a professional...
