"For older games -- especially well-known ones -- it is generally safe to assume that the current listed render API is accurate."
Actually, based on my tests, a lot of older games have wrong API listings. I've been slowly going through them.
For example, the Direct3D 8 list had quite a lot of 2000 games; ALL of them were wrong.
For 2002 D3D8 games, ~21% were wrong. 2001 was quite higher but I don't have a percentage right now.
EDIT: Looked it up. ~60% of 2001 D3D8 games were wrong!
