One of the best games ever. You can replay it numerous time due to variable combat mechanics which almost doesn't restrict you in your ways to achive your goal. Only a decade later BotW introduced arguably better mechanics.
The game has perfectly balanced "atmosphere" which is achieved by wonderful sound design, realistic physics of protagonist's movements and proper mixture of dark and light levels. I just adore orcs island aestethics with all its cliffs, caves, sea and the blue skies. Hovewer outdated graphics is but game design easily overcomes any such shortcomings.
Aside from mechanics the game actually has involving and dynamic story with a major plot twist and choices of romantic interest as well as final decision.
The main characters are also quite interestingly written. The anthagonist is very intelligent and civil, if not charismatic. The girls are written in kind of a smrt and misleading way. I like that majority of the gamers hate Leanna and fall for Xana ignoring the in-game hints about the consequences of such choice. I mean it should be so since Xana is an experienced Succubi and players by default should fall for her sedduction. Also it can be quite challanging to protect Leanna in some missions and she may behave preachy which might lead to consider her annoying and useless compared to Xana. But if you closely pay attention to the small details in the game - rad the books abot in-game entities, carefully listen to the dialogues - you'll know what choice is right and what choice will lead to destruction of the protagonist.
