A great story but an agonizingly, slow, slow, slow pace.
The other faults can be broadly categorized under one item. Simply put the game's pace is interminable. Slow. Endless. Never-ceasing. This slowness manifests itself in many ways.
1) Main character cannot run forcing you to walk (stroll) everywhere.
2) Conversations cannot be cut-short (no use of the escape key) so once started you're stuck.
3) No shortcuts from location to location
4) Screen changes have a quirk whereby the move icon dissappears when the new screen appears - making you wait until the icon re-appears.
5) Cut scenes cannot be skipped.
If you have limited patience and prefer games that move at a reasonable clip, you'll dislike this game intently. If you are a meticulous investigative sort with the patience of a saint and a need to know, you might like this game.
I finally succumbed to a walkthrough, not because the game was that hard, but because I didn't have the patience but I wanted to know what happened.
I gave this a 6.5 only because the slow pace made me feel that I was suffering some sort of endurance test to slog my way through. The addition of a run mode and a way to cut-short the conversations would have boosted my score to a 7.5.
