That Which Is Not Forbidden: The Spectrum of Allowance
When Grand Theft Auto III came out, it introduced a new interaction to the series: players could now solicit prostitutes and then kill them to get their money back.
“To engage with prostitutes in the game, all the player had to do was pull up to certain scantily clad women, who would enter the vehicle in exchange for a sum of money. . . . Disturbingly, players found they could reclaim their cash by simply killing the prostitute with their car after she’d exited."

This capability persisted in later games in the series and gave rise to a lot of discussion. Much of the commentary was careful to point out that murdering prostitutes is not required at any point. But of course Grand Theft Auto games are exactly that: games. You don’t have to play them at all. And they’re known as games where a lot of the fun comes from messing around in the sandbox, going on murder sprees that are also thoroughly unrequired. So is there a meaningful distinction to be made here?
I think there is. Merely pointing out that you can do something in a game is incomplete. It treats it as a binary, with the action either allowed or disallowed. But game design is much more subtle than that. There’s a wide range of how allowed an action can be.
