Are both Fresco and Torres german based board games?
yes
Title: Torres (board game)
Passage: Torres is a German-style board game designed by Wolfgang Kramer and Michael Kiesling and published in 1999 by FX Schmid in German and by Rio Grande Games in English.  The game strongly influenced Kramer and Kiesling's Mask Trilogy of games, but is not considered to be a part of the trilogy.  The game has since been reprinted (in 2005).
Title: David Parlett
Passage: David Parlett (born 1939) is a games scholar, historian, and translator from South London, who has studied both card games and board games. His published works include many popular books on games and the more academic volumes "The Oxford Guide to Card Games" and "The Oxford History of Board Games", both now out of print.  Parlett also invented a number of board games, the most successful of which is Hare and Tortoise (1974).  The German edition was awarded Spiel des Jahres (Game of the Year) in 1979.
Title: Fresco (board game)
Passage: Fresco is a 2010 designer board game by Marco Ruskowski and Marcel Süßelbeck.  It was nominated for the 2010 Spiel des Jahres award and won the 2010 Deutscher Spiele Preis.  Each player in Fresco takes the role of master painter attempting to restore the fresco on a cathedral ceiling, earning points for each section they repair.  Players must manage a team of apprentices who will buy or mix the required paints, paint portraits to earn money, and keep the bishop happy.  Overworked apprentices may leave the painter's service, reducing the actions the player can take.  A player can improve morale, and even gain extra actions, by letting his workers sleep late.  However, this can allow earlier players to block his ability to buy necessary paints or to restore a section of the fresco before he can get to it.
