What's the first anime adapted from a galgame?
Anisearch allows us to filter anime based on the type of material adapted.
Using the more general term of visual novel as a category, the 2-episode OVA Rance from 1993 seems to be the first anime adapted from such a medium.
This OVA is very loosely based on the erotic RPG series of the same name (potential NSFW content).
It depends on what is meant by galgame, but a web search suggests* Dragon Knight is one of the oldest. The game is released in 1989 and animated in 1991.
* a source, you may not be able to see it depending on location
As far as I remember, it was To Heart (1999) that established these kinds of anime on TV.
Technically both Sentimental Journey (1998) (based on Sentimental Graffiti) and Night Walker (1998) came earlier as far as TV anime based on a Visual Novel go. But not every VN is a Gal Game and I do not think either of these does qualify.
Same for Rance and Dragon Knight. They aren't really Gal Games. At least not if you think of a Gal Game as one where you are a guy trying to get a girlfriend among a selection of heroines through choices you make interacting with those heroines.
