One of my first true next-gen experiences, Trespasser (released in 1998 by Dreamworks) featured abysmal gameplay and was almost unplayable thanks to something resembling an interactive, virtual hand. This original take on controls made everything extremely difficult; picking up an object was hard enough, let alone aiming a gun. Now, add some dinosaurs and a pre-historic physics engine and you get a FPS that is impossible to forget, although not in a good way. However, in its attempt to immerse the player it somehow manages to intrigue and frustrate at the same time.
