Illusion (pre-2018)

Illusion (Japanese: イリュージョン, Hepburn: Iryūjon) is a Japanese video game developer specialized in eroge games, founded in 1997. They were infamous for releasing a lot of titles with reused assets (prior 2018), and some of adult-only titles such as Battle Raper and RapeLay.

Originally, their games were not allowed to be sold or used outside Japan, due to the censorship laws, and official support was only given in Japan. However, with the release of Honey Select Unlimited in coordination with the online English erotic game storefront FAKKU, Illusion's policy has since changed. Prior to this change in policy, they were often translated and released in English and other languages by fans.

Why They Used to Suck
Note: Most of these qualities were applied to pre-2018's Illusion.
 * 1) The main problem of this company is that they put less effort on their games, caring more about quantity over quality, resulting in a lot of mediocre to bad games.
 * 2) The graphics of most of their games are horrible and outdated, with an extremely poor model quality, even by 2000s and 2010s standards.
 * 3) Speaking of which, Illusion reused several assets in most of their games, especially the character models, that lack any kind of detail and expression whatsoever.
 * 4) Prior to 2018, they published a large amount of titles with overpriced price tag for its content. For example, Battle Raper 2 costs ￥9.500, which is around $85, even by the fact that is just a generic Soul Calibur-style game.
 * 5) Most of these games have poor gameplay and only a few enjoyable elements, which can bore the player overtime. Like Artificial Academy, which the player have to interact with other students to befriend them, and have sex with your lover.
 * 6) Their games have, at a lot of times, disturbing material or revolve around a disturbing premise (an infamous example is RapeLay), somehow due to poor quality of the graphics it makes the experiences even more uncomfortable.
 * 7) *Also, some games that doesn't have questionable content, has boring and generic plots you can expect from a eroge game, like Artificial Academy and School Mate, that has the high school plot, which is a very overused plot in a eroge game.
 * 8) The voice acting of most of their games are mediocre to horrible, especially during the sex scenes.
 * 9) Due to the controversy around RapeLay and the censorship laws in Japan, several games made by Illusion were banned or not intended to sell outside of Japan, which means that you can't play a game in another language besides Japanese, unless you use mods.
 * 10) The sex scenes are not pleasant to watch, mostly about how badly animated are, and not mentioning that some games involves rape, which makes these scenes very unsettling to watch.
 * 11) * Also, because of the laws in Japan about erotic content in media, you can't see the genitalia of the characters in games, which makes the sex scenes even less enjoyable.

Redeeming Qualities

 * 1) Their game engines are quite moddable, many of them having been produced on the Unity engine, and they do nothing to discourage the modding community. In fact, they encouraged their fanbase to translate their game to made it more accessible as well.
 * 2) Most games were never intended to sell outside Japan, and the ones that have tend to be their "tamer" (in terms of content) games.
 * 3) After all of hit-or-miss titles, in 2018, they've published Koikatsu, which is one of the best eroge game of all time, which were featured one of the best character customization system, and offered a huge amount of content with "uncensored" patch.
 * 4) Due to the success of Koikatsu, Illusion has "reformed" themselves by focusing on quality over quantity and put an effort into making games, most notably in AI Shoujo and Honey Select 2.
