I'm already making a game, have been for a while now.
Some people jump into creating perverted games, short stories, or illustrations because they want to scratch some of the money involved into it. That makes them whore away their creations and do crazy things they don't even like and wouldn't normally do. But they do it to try to get some money.
Others are just closeted perverts who want to escape their -according to them- annoying and boring life, and partner, and family, and so on... Some people are so desperate to escape normal rules and regulations that they end up doing crazy things when they think they can get away with it, lately we can see that clearly in the news.
Is great when someone creates something because is a theme they're familiar with and is the story they wants to tell, but most authors this days make stuff just to sell, even if they don't know anything about what they're making or they don't even like what they end up doing.
But anyway most people out there are like "I don't care about the story I just want to fap (retarded laughs)".
