I think there are enough disparate entries in this series to merit a franchise page. Examples from multiple games would be listed there, along with a basic history and links to these sepparate pages:

• Prince of Persia (1989) for the original trilogy.

• The Sands of Time Trilogy
  • Prince Of Persia The Forgotten Sands may or may not have it's own page.

• Prince of Persia (2008).

• The 2010 film adaptation.

• And the 2008 graphic novel written by Jordan Mechner
