Claims

• Adolescents who engaged more with Crystals' empathy training mechanics showed greater increases in empathic accuracy-related RTPJ activation, controlling for total playtime [+M]
• Crystals gameplay increased DMPFC–posterior cingulate resting-state connectivity relative to Bastion, specific to the empathic accuracy-related network [+M]
• Improvements in empathic accuracy after Crystals gameplay were associated with strengthened amygdala–MPFC resting-state connectivity relative to Bastion [+M]
• Playing the empathy training game Crystals of Kaydor produced no greater improvement in adolescents' empathic accuracy than playing the commercial control game Bastion [~M]
