We take a look at the rather cool Gabriel Knight Sins of the Fathers 20th Anniversary Edition demo in this walkthrough video which highlights the much improved graphics from its original game which released way back in 1993. With the original designer Jane Jensen on board, the game is a joy to play for point and click adventurers. If you’re interesting in getting to grips with the full game, then be sure to take a look at the official website for more details.
