The term "[=doujin soft[ware]=]", also known as "doujin games", refers to a sub-genre of {{doujinshi}} -- essentially, self-published video games. They can be considered Japan's equivalent to an IndieGame; while the term "indie" exists in Japan, it is a relatively new concept which refers only to games released through commercial channels.

Doujin games are generally released for Windows-based computers, and, like doujinshi, doujin soft may offer games based on one or more intellectual properties, or entirely original works. The most frequent genres seen in this category of games are {{platformer}}s, {{fighting game}}s, {{RPG}}s, [[ShootEmUp shoot 'em ups]] (often BulletHell shooters), and {{visual novel}}s. These games are often released at special Japanese conventions, such as the Comic Market (a.k.a. Comiket) and Reitaisai. Depending on the game's subject matter, they can also be considered fan games (e.g., ''VideoGame/GriefSyndrome'' to ''Anime/PuellaMagiMadokaMagica'') or a {{Homage}} to another favorite franchise (e.g. ''VideoGame/{{Rosenkreuzstilette}}'' to ''VideoGame/MegaMan''). Most of the time, doujin game developers manage to avoid getting {{screwed by the lawyers}} concerning the use of another franchise, while a few others aren't so lucky. Case in point: ''VideoGame/RockmenR''.

Doujin gaming has been around for a very long time. One of the most prominent (and well-known) long-runners of the doujin scene is the ''VideoGame/{{Touhou}}'' series, with its first entry debuting in 1996; since then, it has expanded across 22 official games in the series and a cornucopia of [[FanWorks/{{Touhou}} fan-games]]. That is not to say there aren't other doujin game series that have contended for such a position and legacy. Other doujin series, such as the ''VisualNovel/HigurashiWhenTheyCry'' series, have even migrated into the realm of mainstream anime and manga.

Obtaining these games, however, can a difficult endeavor for those outside of Japan ([[FreewareGames freeware]] ones are easier to get), given the level of obscurity of certain titles and limited print runs. There's also the matter of the games themselves being in Japanese, which can problematic if it's very text-heavy (usually in the case of visual novels and [=RPGs=]) or [[GuideDangIt when a game requires you to learn something you can't read]]. Often at times these games get [[FanTranslation translated by fans]] with the knowledge of the Japanese language and the proper know-how of hacking, editing, and re-programming a game to run in a completely different language, and the willingness to do so. Also, some games are ''already'' in English and comes with English documentation, which makes playing them easier.

In recent years, there have also been a very small but growing number of publishers, independent or otherwise, that localize these games outside of Japan and bring them overseas. There are also a few specialty online retailers that can import the original pressings of a doujin game, if copies are available in stock and if shipping the game in question isn't taxing on your wallet. Additionally, some doujin games have been re-released and localized digitally through digital distribution services such [=DLsite=], Playism, and UsefulNotes/{{Steam}} to make things easier for those who could not attend to the events where they were released in and alleviate the cost of importing the games overseas.
