^^no offence but first of all you tell me what do you mean by "ppl wont buy the old pop game"
A true fan will surely do that.i am not a fan but still i have bought and i know few who also have bought it.
pop sot, pop ww,and popt2t were classic.If you know pop history then this is the series which have completed the pop story succesfully.
Pop sot still holds the best storyline ever.
pop shadow and the flame (dos) needed a sequel but it was cancelled.
Prince of persia mainly succeeded due to its amazing storyline and the great acrobatic moves.
If you spoil one then the whole game will be disturbed.
the two thrones succesfully ends the story of pop triology.
Then why they are putting some meaningless story in between and trying to expand it.in case you dont know the storyline of forgotten sands then search for it.it's nowhere near the other series.it has only few new moves and options thats it.
Business can be done in other ways also.Eg:- assassins creed 2.instead of touching the pop series.they should pay more attention to assassins creed series now.
