I remember this game all too well. Beautiful visuals, the storyline was great, and I loved the platform puzzling to death. Exploring a location and figuring out where to go next is an absolute joy, and then pulling off the combo of moves to get there is always a buzz.
Then there's the combat.
Seriously, I hated the combat with a vengeance, especially later in the game. You quite often get surrounded and just pinned to the ground until you are dead. Then you knock someone over and can't get to him in time to apply the dagger to finish him off, so he gets up again. Or you kill someone and then another bad guy spawns in. Seriously, the last time I played this, I finished off literally screaming incoherent insults at my PC until I decided it was better to uninstall and save my sanity.
Seriously, this game would rate higher if the combat was handled better. Otherwise, I'd only suggest it for the very patient.
