These devs would be sorted for life if they actually stuck to it the whole way through. So much potential with so much encouragement right from the off, with money streaming in, in a way that most could only dream of. Give that opportunity to your average, everyday Joe Bloggs stuck in the rat race and he'd bite your hand off before you could finish the sentence.
Of course, there is a lot of skill, knowledge and time that goes into making these games, I understand that, but one could live off the income while the game is still under development without ever having most of the problems of 9-5, blue-collar or any other normal over-demanding, under-paying jobs with bosses to answer to. It's a get-rich-quick scheme for all intents and purposes, let's not get it twisted. I don't know of any jobs provide opportunities with an offer that lucrative. Yes, you are feeding off of (some) people's (uncontrollable) fetishes and kinks and a lot of people will pay unreasonable amounts of money to experience them but it's their money and hardly a moral endeavour in the first place to worry about that sort of stuff, no one is really forcing them to pay anyway, these people could easily enjoy all their whims and desires for free from sites like this.
The games don't even need to be that good all the way through so long as they finish with a decent story (and from what some of these devs come up with, they know what they're doing), people just want to experience a complete story with an ending with good-satisfactory writing.
If some of these devs can't handle even this level of pressure where fans aren't actually asking for much and actually are only holding the developers to their own words, then they're in for one hell of a rude awakening when they have to get normal jobs (because they couldn't hack the pressure of porn game development...) in the real world where it's dog-eat-dog and no one cares about your feelings.
