Game Dev Story

Game Dev Story, their 1st English release

Among English speakers, Kairosoft is mostly known for its mobile simulation games, which are released on the Android and iOS markets. Their first western release was Game Dev Story in December 2010. The game was a hit, becoming one of the top 10 games in the iOS App Store in about a week. Since their 2010 debut, Kairosoft has translated and released over 25 games for the English market.

While Kairosoft's Western storefronts are limited to the Android and iOS app stores, the company has developed for other platforms in Japan including PC, DoCoMo, and Softbank. Today, they still develop for DoCoMo, Android, and iOS. The recent trend is for a title to be developed for DoCoMo, ported to Japanese Android and iOS, and then translated/ported to English Android and iOS.

Pocket Academy ZERO

Meimon poketto gakuin 1 is available for Android

The Android markplace often gets games before the iOS store, and sometimes gets untranslated games unavailable to iOS purchasers such as Card Change and Meimon poketto gakuin 1. Although the Android store has received more unique games, the iOS versions tend to be cheaper. Additionally, iOS apps allow the user to switch freely between English and Japanese translations, rather than requiring separate purchases as the Android store does.

Starting in early 2016, Kairosoft started porting all their previous and new games into the Unity game engine. This allowed them to streamline their development process, as it allows them to port games easily without rewriting it for multiple operating systems, and also offers other benefits (such as custom fonts instead of making all special fonts images of numbers and letters).
