Yeah, imagine having your family around you all day and night, because they can't GO ANYWHERE. Why would that be an obstacle for making a sex game on your computer for hours and hours.
*Young daughter walks over to her father at the computer* "Daddy, what are you doing?"
*Father waves her away* "Daddy is just trying to the lighting on this load of cum inside this girl's pussy just right. Go bother your brother."
The quarantine can both be very good or very bad for a game developer. People just seem to jump straight to "Lol, everybody is now at home all day, so he should work on his game all day, no exceptions!"
Not many people seem to think about "Hmm, if the guy has a family, they are now always home, which doesn't exactly make it easy to render sex images on your computer for hours and hours every day." He MIGHT be able to do a few at night, when the family is sleeping, but then again: He needs sleep as well, and probably can't sleep at day & work at night, when the family is home, because he needs to look after the kids and help with housework.
Also think about the possibility, that most of these people aren't making a ton of money, and that they are looking at the risk of losing their job/house/health/whatever, which also does NOT make game development a priority.
I understand why people might be getting impatient with some devs, but keep in mind that this lockdown is making it HARDER, not easier, for a lot of these developers to make these kinds of games. It's always easy to tell a homeless man "Just buy a house!" until you become a homeless man and discover, that life ain't that simple.
