In some of the early erotic games, the erotic content is meaningfully integrated into a thoughtful and mature storytelling, though others often used it as a flimsy excuse for pornography.
Oftentimes, voice actors who have voiced for eroge have been credited under a pseudonym.
The eroge company Nitro has a division that produces exclusively BL games, known as Nitro CHi RAL.
They have produced the BL games Sweet Pool, Lamento: Beyond the Void, Togainu no Chi and Dramatical Murder, each one of the last two have been given a manga and an anime adaptation.
Eroge was much less common on consoles - only NEC's PC Engine series had officially licensed adult games, and from the mid-90s, Sega's Saturn.
Both Nintendo and Sony disallowed adult video games on their consoles.
Soon, new genres were invented: ASCII's Chaos Angels, a role-playing-based eroge, inspired Dragon Knight by Elf and Rance by Alice Soft.
