While FRACT OSC is largely a low-risk game, the open-ended nature of music creation could lead to extended play sessions (infinite play). There are minimal social risks, primarily related to potential social comparison when sharing creations, but no direct stranger interaction or competitive toxicity. Content risks are very low, with only a mild sense of unease from exploring an abandoned world.
