Your Diary + is a 2018 narrative adventure game from Japanese developer Cube, available on Steam with Simplified Chinese as its dominant audience.

This title sits in a curious position: modest residual revenue, a 85%+ positive rating, and a player base that is overwhelmingly Simplified Chinese-speaking (248 of 359 reviews). The core appeal appears genuine, but localization quality concerns and the studio's apparent dormancy create friction. A revival or licensing play targeting the Chinese market directly, or a full localization pass into English, could unlock meaningful upside; catalog acquisition alone carries execution risk unless the buyer has regional expertise or localization capacity. Most realistic play: revival.

• Risk: Critical mass of player feedback cites translation issues in Simplified Chinese, the game's primary market, creating friction despite strong sentiment scores.
• Risk: Developers (Cube, status ghost) last posted roughly 90 months ago; infrastructure, backend, and platform dependencies may require audit.
• Risk: Median playtime of ~35 hours suggests high engagement, but current active player count (1-5 peak/month) implies word-of-mouth has stalled; revival requires marketing fuel.
