Maybe in the full game we will get inspiration points for making choices that agrees with our alignment.
And how do they defined those?
Take the Paladins of Tyr. What is actually the good/neutral/evil choices there?
Believing the Paladin of Tyr? Unless you pass some DCs or talk to some corpse, they are goods aligned so their quest should be too.
Believing the target? How do you know that person is saying the truth?
Killing everyone? This is actually a good option based really, maybe a bit chaotic, but good. Could also be an evil option. Really depends why you are killing everyone...
How to you manage true neutral alignment? Giving points because people are skipping quests?
I do agree with previous posters that suggested that if alignment had to do anything, it would be the facial expression in scenes. Evil characters shouldn't look so affected by unknown people dying...
