Alpha Protocol - Similar But Different From ‘Mass Effect’

 Little interview on MTV about the little diffences.

For one, “Alpha Protocol”’s dialogue tree, dubbed by Obsidian as the “Dialogue Stance System,” has timed responses. As players take on the role of super spy Michael Thorton, they will have control of Thorton’s reactions and interactions with other characters via the dialogue system. While there are a few options to choose from, including nice and aggressive responses, the player must choose quickly and carefully. Decide too slowly and your character will revert to saying something that suits the previous stance you selected. Also, non-player characters will not always react in the same way. Rucinski told me that conversations are “cinematic presentations,” and players won’t always have the same conversations. Players will also have a detailed chat log to refer to.
