Discussions surrounding addiction are often fraught with difficulty, largely due to a societal framework that has historically criminalized substance use disorders rather than treating them as a public health crisis. For over half a century, the American "war on drugs" has perpetuated a narrative that portrays drug abuse as a moral failing, leading to people struggling with these illnesses being stigmatized as irresponsible or dangerous. This cultural perception fosters shame and secrecy, making it challenging for individuals to openly address their experiences with addiction.

In such an environment, art provides a crucial outlet for exploration and expression that societal norms often suppress. Video games, in particular, offer a uniquely powerful medium to simulate and engage with the compulsive and all-consuming nature of addiction through their inherent interactivity. Through choice-based narrative qualities, games like Katana Zero, Lisa: The Painful, and Kentucky Route Zero respectfully and empathetically depict the complexities of substance use disorders. This approach can help players develop a deeper understanding and process the role of addiction in their own lives, offering a safe space for contemplation.

The effective portrayal of addiction in games often hinges on the strategic application of player agency. For instance, in the neo-noir action platformer Katana Zero, the game employs a timed NPC dialogue system. Players are presented with typical branching dialogue options but also have the unique ability to interrupt characters mid-sentence. This mechanic allows the player to influence how the protagonist, Zero, interacts with others and presents himself. Crucially, while players can dictate Zero's actions to an extent, they cannot fundamentally alter his core identity or struggles, mirroring the defined and often unyielding nature of battling an illness. This nuanced control over expression within a fixed character framework effectively simulates aspects of living with addiction.
