Well im playing the first Assassin's Creed again to get myself ready for the second, which is coming out for PC soon, and i thought of a few questions. 
  

AC1

•  In the first game, when you climb towers and view areas to spot investigation missions, lets say i exploit all of those viewpoints at once (use all of them by climbing and viewing), doesnt that ruin it for my next mission in this town since i already climbed all the towers or is this where the blue light limitation saves the day ? 

AC2 

•   Can you skip the cutscenes in AC2?
•   I'm pretty sure that in the first game, you couldnt jump from a low roof / ledge and stick your hidden blade into a guy's neck all in one move, like here  :

You can jump onto people with your hidden blade in AC1..

• I don't understand your first question.
• I believe so, yes.
• You certainly can, that's like, on every fucking gameplay video there is.

1.  Yes, the blue limits come into play in AC 1 to keep you from doing everything at once.
2.  Yes...?  Maybe.  I can't recall
3.  Yes.
