What I mean is, in terms of settings. From the Gamescom demo you hear about Altair's father and how he was also an assassin. Could it be that his father was not born into the order like his son? Is it possible his father came from another region before moving to the holy land? Was his mother also an assassin?
I have not played the "prequel" on the nintendo DS, but I remember hearing his father was muslim and mother was christian.....or was that someone else? The AC wiki also claims that his father died when Altair was 11 years old, but says nothing about his father's past. 
 
If Revelations allowed you to play as Altair's parents, would it be possible to have those sequences be in a completely different setting? Or even have his parents be Templar turncoats (big revelation)....

The first game takes place around the middle ages, somewhere around 1200 AD right? Well seeing as the Arabians had spread pretty wide already back then, Al-Andalus or "Islamic Spain" having been conquered by them for about 5 centuries already, it could be likely that his father came from a different country.

Desmond killed Altair's "father" from the future and slept with his mother, becoming his biological greatx45 grandfather. This unique genetic code is how he was able to use the animus, which was actually a gateway through time. His mind, sent into the past, to learn things from his Assassin background, so he could be the ultimate Assassin.

He is also subject 16, time-lapsing through his own mind to regain control of what he thinks he really is. But now his world is flipserd upside down.

You know, I think the sad part is, this sounds like some shit that could actually happen in an Assassin's Creed game.

What part do Altair's parent play in Revelations? I don't think they will play any more than past games, as in none...

If I recall, his mother died in Childbirth. As for his father, he has only ever really been discussed in a book and we may learn more in Revelations if Altair talks about his past more. Odds are Umar was born into the Brotherhood as well though since the Assassins Order was established in the general area for at least a century and at this point in time was heavily centralized.
