A JRPG protagonist decides that instead of punching God in the face he wants to turn her into his little sister. And so he must assemble a coterie of sister tulpas on his quest to collect photo albums, steal the mail, and have Vietnam flashbacks about sisters he doesn't have outside of the confines of his headspace. 9/10, on one hand it's a wonderful example of why AI is a tool like any other used to create, as well as the current exception to the rule when it comes to the predominantly mobile auto-battler style of game. On the other hand I'm reminded of the 2010s and how the happening trend in anime for several years was brother-sister incest. Which is a Class C Felony in Alabama while being legal in Rhode Island, Ohio and New Jersey. Explains a helluva lot about [i]The Jersey Shore[/i].

Promise with My Sister is a small-scale indie RPG that blends light strategy, exploration, and character progression into a gently paced adventure built around themes of family, memory, and perseverance. Developed and published by Carnival Pepper, the game sets itself apart less through mechanical complexity and more through the way it frames its systems around a personal, emotionally grounded premise. Rather than presenting a sweeping epic or high-stakes fantasy war, it focuses on a quieter journey that emphasizes bonds between characters and gradual growth over time. The narrative centers on a brother who sets out on a journey tied closely to promises made to his sisters and the memories they share. This premise provides both emotional motivation and structural direction, as much of the game revolves around protecting, supporting, and progressing alongside these characters. The story unfolds in small pieces through exploration events and collected memories rather than long stretches of exposition, giving the experience a reflective tone. While the plot is simple on the surface, it serves as a consistent anchor that keeps the player engaged with the game’s goals and progression. …
