The bundle includes four titles: \"Game Dev Story++,\" \"Manga Works,\" \"Dungeon Village,\" and \"The Heian City Story.\" It is priced at 998 yen, a 78% discount off the combined regular price of 4,533 yen. The company notes that the 30th anniversary refers to its first appearance in the PC game magazine \"Tech Win\" in 1996, while its incorporation dates back 18 years. The bundle is a limited-time sale, with plans for up to four volumes. However, the store page warns that the sale will end \"if the president finds out and gets angry,\" a recurring joke in Kairosoft's Steam promotions. The four games cover different simulation themes: running a game company, training a manga artist, building a dungeon, and developing a Heian-period city. All are rendered in Kairosoft's signature pixel art style.","whyItMatters":"The bundle's 78% discount and the company's self-deprecating joke about the president ending the sale are the main hooks, but the real story is that Kairosoft is using its 30th anniversary to push a curated set of its older simulation titles onto Steam at a price that undercuts buying them individually.","webCardHtml":"\u003cp\u003eKairosoft's mascot character Kairo-kun issued a message alongside the bundle announcement, noting that the company's 20th corporate anniversary will arrive in 2027. \"In 2027, we'll be celebrating Kairosoft's 20th anniversary as a corporation... hehe,\" the message reads. The company released a commemorative illustration that it says it \"hurriedly made yesterday.\"\u003c/p\u003e\n\u003cp\u003eThe bundle's four titles each carry individual Steam prices that make the discount steeper than the headline 78% figure suggests. \"Game Dev Story++\" is currently on a separate 63% discount through June 14, bringing its individual price to 473 yen. \"Manga Works\" and \"Heian City Story\" are each 1,280 yen individually, while \"Dungeon Village\" is 1,500 yen. The combined regular price across all four games is 4,533 yen, meaning the bundle at 998 yen represents a 78% savings. Game Spark reports the total regular price as 5,340 yen, an 81% discount, though that figure appears to exclude the separate sale on \"Game Dev Story++.\"\u003c/p\u003e\n\u003cp\u003eKairosoft is a studio founded in 1996 that specializes in pixel-art simulation games. Its representative works include \"Game Dev Story++,\" \"Dungeon Village,\" and \"Dream House Days\" (also called \"Pocket Stables\" in some regions). In 2024 the company released \"Doraemon's Dorayaki Shop Story,\" a collaboration with the Doraemon franchise. The studio's games support up to 14 languages and have quietly built a global audience through game streaming, according to the company's press materials. Most of Kairosoft's Steam releases hold a \"Very Positive\" or higher user rating.\u003c/p\u003e","blueskyPost":"Kairosoft's 30th anniversary bundle counts from its 1996 magazine debut, not its incorporation 18 years ago.
