Oh wow, that's a nice explanation man. Actually I am facing the spoken language issue in the game and that's why it's a bit hard to understand the concept. Once I am done with the actual version of the English language, I will play the game completely.
Btw ezio became old in revelation.
Ezio's actually only around 5 years older from the ending of AC Brotherhood. at the ending of brotherhood he is around 48, in AC Revelations (beginning) he is around 52-53
