viviON GAMES Cloud Service Launches August 26

viviON, the parent company of DLsite operator Acis, announced on August 20 that its new cloud gaming service, viviON GAMES, will launch on August 26. The service lets users play PC games on smartphones through a browser, without downloads or complex setup. It uses viviON's OOParts Engine to run PC games on dedicated servers, meaning developers do not need to port their titles to mobile. The service uses a per-game purchase model rather than a subscription. The announcement image shows the aquarium horror adventure "Aquarium wa Odoranai," suggesting it will be a compatible title. The service was first announced in May, and trial exhibits were held at the indie game event BitSummit PUNCH, where seven titles were playable, including "Yomawari 3," "Seifuku Kanojo," and "Shironagasujima e no Kikan." viviON also released survey results estimating that 11.7 million people in Japan, or one in five adults in their 20s to 50s, are "former PC gamers" who stopped playing on PC. The company calculated that their departure represents a lost market of roughly 100 billion yen annually.

The survey behind the 11.7 million figure ran from August 7 to August 12 using Rakuten Insight's panel. The screening phase reached 10,000 men and women in their 20s to 50s nationwide, and 1,000 of them who said they had played PC games in the past but stopped were given the main survey. Weighted back tabulation used gender and age ratios from the Ministry of Internal Affairs and Communications Statistics Bureau's "Population Estimates" as of October 1, 2024. The 20.2% occurrence rate was multiplied against a population of about 58 million people in that age range. Men in their 40s (25.6%) and women in their 20s (20.7%) showed the highest rates. The lost market calculation starts from spending data: 37.5% of former PC gamers (45.6% of men, 25.0% of women) had bought titles or made in-game purchases, with a median annual spend of 24,000 yen among those who did. Multiplying the 11.7 million figure by the 94.7% who had stopped for over a year (about 11.08 million people) and the purchase-experience share produced the roughly 99.8 billion yen annual estimate. The departure reasons break down further than the summary states. "Employment or job change" led at 33.7%, followed by "advancing to higher education or graduation" (20.5%), "childcare or childbirth" (19.6%), "marriage" (15.8%), and "changes in work environment such as promotion or transfer" (13.0%). viviON is a company under Geo Holdings, established in 2021 through the group reorganization of Acis. It also runs the digital comic distribution service comipo and the VTuber production Aogiri High School. The brand message is "That game, right now on your smartphone."
