looking to begin preservation of 18+ games, and games associated with the genre through their production companies.

Illusion Software was the big name in 3d Japanese Eroge in the 00s through the early 20s. they've since dissolved and reformed, so a lot of their works are going to begin entering that disillusion phase as the works that were purchasable are delisted, and materials are lost.

I'm trying to get as much of the promotional and release materials as possible in the Launchbox DB until a 18+ exclusive archival service becomes available.
