This is probably a niche topic on HN, but for those of us who play Visual Novels, VNDB is a massive resource for getting the setup right for older and obscure ones that require odd hardware or configurations. The early days of VNs were all on DOS/V and Sharpx68000 systems with quirky configurations. VNDB catalogs so many of them and things that are "Mostly" VNs for historical purposes.
Without it, we wouldn't have the modern wave of VNs that have become popular today (Hatoful Boyfriend, Doki Doki Literature Club, etc.) nor some of the offshoot genres that have become popular.
