I played the 20th Anniversary remake of the first #GabrielKnight game and it was pretty dang good. There are parts of the game that don't age super gracefully, even with the benefit of the remake (GK is a giant horndog, like Leisure Suit Larry levels of horny) but the main plot isn't one of them.
I also forgot how rooted these early Sierra adventure games can be in history. Like I literally learned things (hopefully not entirely untrue) playing this game.
