Despite the coincidence of the new game's release date to that of the movie, this doesn't look like it will be a simple movie tie-in; at least, I don't think you can expect the in-game prince to look like Jake Gyllenhaal. But he won't look like last year's rogueish non-prince, either. This game is said to be a "return to the Prince of Persia: Sands of Time storyline" and "will feature many of the fan-favorite elements from the original series as well as new gameplay innovations that gamers have come to expect from the Prince of Persia brand," in the words of the press release. Whatever elements those are.
That's about all there is to know at this point, though we'll get a look at the game itself in a couple of weeks here when it premieres on the Spike TV Video Game Awards. Maybe I'll finally remember to fire up that Epilogue DLC for last year's game before then.
Since we don't actually know anything concrete yet, what would you want to see in a new Sands of Time game? Let's assume "less baditude" is implicit in that question and go from there.
