Jurassic Park: Trespasser was an ambitious game with plenty of unique features for its time, among them a physics engine, realistic water, a complex environment with lots of trees, and an almost nonexistent character model that has only one arm that stretches out in an awkward fashion. Unfortunately, the game had a rushed development cycle and got released in a broken state that received negative reviews and sold poorly. Still, it has a dedicated fanbase.

To do:
There's probably a whole lot more unused content, plus there's the leaked source code.
