However, most pregnancy-related digital interventions target specific behaviors and do not provide a comprehensive, longitudinal simulation of the pregnancy journey that incorporates psychosocial and administrative aspects.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec sec-type=\"objective\">\n                    <jats:title>Objective<\/jats:title>\n                    <jats:p>This study aimed to develop and evaluate a narrative-based serious game that simulates the chronological course of pregnancy and to assess its perceived educational usefulness, accessibility, and user acceptance across multiple platforms.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec sec-type=\"methods\">\n                    <jats:title>Methods<\/jats:title>\n                    <jats:p>We developed a 9-chapter interactive serious game covering pregnancy recognition, partner communication, public health consultation, mid-pregnancy and late-pregnancy checkups, and home preparation for childbirth. The game was collaboratively created by a pediatrician, 6 medical students, and a student illustrator using a low-cost visual novel engine (TyranoBuilder). It was released in April 2025 on iOS, Android, and Steam. A voluntary, anonymous postgame survey was conducted between April 2025 and January 2026. Descriptive statistics were used to summarize survey responses and platform analytics. This study was approved by the Ethics Committee of Shinshu University Hospital.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec sec-type=\"results\">\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>A total of 65 users completed the postgame questionnaire. Most respondents were aged 10 to 19 years (38\/65, 58.5%) and female (55\/65, 84.6%). Nearly half of the participants (30\/65, 46.2%) completed the game within 1 hour. Gameplay evaluation scores (5-point Likert scale; 3=neutral or appropriate) were balanced: game length (mean 3.37, SD 0.96), difficulty (mean 2.84, SD 0.85), and interactivity (mean 3.31, SD 1.10). Educational outcomes were rated highly (5-point Likert scale; higher=more favorable): reduced anxiety (mean 3.84, SD 0.96), perceived educational usefulness (mean 3.98, SD 1.02), perceived knowledge acquisition (mean 4.06, SD 1.06), story empathy (mean 3.80, SD 1.11), and overall satisfaction (mean 4.05, SD 1.04). Across all platforms, the game achieved 925 cumulative downloads. iOS and Android downloads were predominantly from Japan, whereas Steam downloads were geographically diverse. Of the 21 Steam reviews, 20 (95.2%) were positive.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec sec-type=\"conclusions\">\n                    <jats:title>Conclusions<\/jats:title>\n                    <jats:p>A serious pregnancy education game developed through a low-cost clinician-student collaborative model demonstrated high perceived educational usefulness, balanced gameplay characteristics, and broad user acceptance, including substantial engagement among teenagers and international users. Narrative-based serious games represent an accessible and scalable approach to maternal health education. Further research using more rigorous evaluation designs is warranted to assess long-term educational and behavioral impacts.<\/jats:p>\n
