Are the remasters not translated? I remember playing Day of the Tentacle, Grim Fandango, and all the other LucasArts games when I was a child, and they were dubbed in French.
EDIT: I checked, and I was mistaken: DOTT was never dubbed in French, but Grim Fandango (and its remaster) is.
Some are, but I'm Danish and I think they translated any of the games to that :)
