I tried play a bit Alpha Protocol and get hurt by many details in its beginning, not sure when I'll try it again:

• The controls seems weird, one key for close fighting and a different key for shooting.
• Just one key for close fighting, that seems extremely basic, is DKS require own a master in action game? And I won't even quote a game like Torchlight.
• There's something very wrong with the camera, not sure why but it's clear many players can be hurt by that point.
• The mood is just cold, and that includes the hero himself.
• The strange action dialog system requiring instant reflex decision is weird. I'll never enjoy such system and will just feel it frustrating to see decisions points disappear because I didn't react fast enough, or will be frustrate by decisions I'll not like just because it's done in hurry. This action pressure on dialogs is I bet something that won't like many players.
• The too clear non adaptation to PC of a console game is something always unpleasant even if not a major point.

That is a lot of immediate unpleasant points that jump on face of the player a long time before the story has any chance to grab him, nor the action to grab his interest.

I could worth a lot, but the sin is the beginning is unattractive and worse, it is repulsive.
