Pros
Pro In game physics provide a sense of immersion
Throughout the game the player is tasked with opening doors, rolling barrels, or pulling open drawers, this is done by using certain mouse motions to complete, so say for instance if one wants to open a drawer they need to not only click on it but hold the click while making a pulling motion with the mouse. It is through this realistic portrayal of interaction that allows one to feel immersed in the game environment.
Pro Intuitive puzzles that can be solved realistically
Penumbra offers puzzles in a realistic setting where if one wants to get pas say some oil barrels, the obvious solution is that you can burn them. It is through using puzzles that ask for logical solutions that the game sets itself apart from many puzzle games where solving is not quite so logical.
