I am absolutely not sure that there are at least a few games on this site (maybe, with rare exceptions, games from illusion), the labor costs for which could be a million, or even half a million.It's not what you said.
"Let the game developer invest his own personal money and create the game."
Meaning if you're not a millionaire you don't get to make games, right? Lol.
DLSite. You can also sell such games in steamWhere do you think the capital comes from before a game is out? No one is publishing porn games.
Studio Illusion generally specializes only in such games and feels fine.
