There was a couple of titles that make me completle loss my sense of time. Blade of Darkness is one of them...

User Rating: 8.7 | Severance: Blade of Darkness PC
I spent many hours trying to understand full potential of this game, and even after 6 years i can't do that. This game totally rocks and breaks the convention of hack & slash games where most of time we spent on clicking LMB. In BoD we must think to survive. Every action has a reaction, so we must think when we fight. Our hero is build from flesh and bones so 2 reckless moves and goblin can do a barbecue from our head. Enemies are wild beast who wants to spill last bead of blood from your body. After 6 years graphics looks awfull, but physics and lights are still surprisingly good. There are 18 levels and every of them is a great mysterious adventure. The most problem can be difficult of this game. It is easy to learn how to move, but it is not easy to learn how to fight...

Anyway...I recommend this game to every ambitious player who loves h&s.
