Gabriel Knight: Sins of the Fathers

While there is some humor in this, the first GabrielKnight adventure, it’s more serious than the other games I’ve mentioned so far. Playing as the titular Knight, voiced by Tim Curry, you investigate a series of sinister occult-like murders in New Orleans. It has a wonderfully dark neo-noir atmosphere, and the deeper Knight digs, the stranger things get. Just avoid the remake and play the original.
