I played all prince of persias made by gameloft on nokia n gage qd and they all was very good quality 2d games, so the gameplay will be different, does it mean that it will be bad ? DS will never have assasins creed good as x-box 360 because ds is to weak for that.
The 360 version wasnt even that good. (i dont say it was bad, but CoD 4 and mass effect where just ALOT better)
So i think the ds version is gonna shuck, even if it is good im am not gonna play it, because i have just finished the console version and im am tired of altair.
