Hentai Heroes, the story-driven, browser-based, free-to-play adult video game from Gaming Adult, has topped the five million player mark, the company announced today.

In Hentai Heroes, the player goes on quests around the ‘Haremverse’ and invites anime-inspired horny and busty ladies to join his harem. The game can be played on a variety of platforms, including HentaiHeroes.com, Nutaku.net and Eroges.com.

Released just two years ago, the growth rate of Hentai Heroes has been both impressive and steady. Gaming Adult announced the game had reached three million players last April.

Reaching the five million player milestone “makes Hentai Heroes one of, if not already, the most played adult game in the Western world,” said Onizuka, Business Developer for Gaming Adult.

Onizuka said the key to the game’s success – and the long-tail revenue generation it offers for Gaming Adult and the affiliates who promote the game – is as straightforward as it gets.

“Our own games are successful because they follow a simple and effective principle: players want a quality product and we give it to them,” Onizuka said. “It’s the oldest trick in the book, but it delivers. We offer our players a steady influx of new content and we constantly work to improve the in-game mechanics. This, combined with the special offers we provide, allows Hentai Heroes to generate long term revenue.”

As part of its effort to encourage continued engagement on the part of the game’s players, Gaming Adult recently announced the addition to Hentai Heroes of a character based on adult performer Sara Jay, making her character the first in the game to be based on a real person.

It’s little touches like the introduction of Sara Jay’s character and the steady addition of new content to the games that inspires player loyalty and the development of a community surrounding the game. In turn, that community has driven the success of Hentai Heroes and the company’s other titles, Gaming Adult Account Manager Magrat said.

“Hentai Heroes has a very engaged online following and an active community. Our players are not only anime-loving gamers, but passionate collectors,” Magrat added. “They love sharing their in-game successes and ideas about new girls and stories. It’s super refreshing to see the players of an adult game so immersed in and its community.”
