Although it's a classic, the graphics and gameplay were rather disappointing. The same character models and environments would be used again and again, making the game very repetitive after a while. Additionally, some of the objectives are not clear: many times I either spent a long time searching for a hidden door or resorted to the internet to find something. My biggest gripe is about its physics. Movement is generally very slow, and collisions are slippery. This made some of the very simple parkour elements of the game extremely frustrating. However, I understand that most of these can be forgiven, seeing that it was made in 2001.
