@Onyxmeth: Prince of Persia can be done in 1 playthrough. Just grab the minimum amount of light seeds needed to complete the main story for the speed run achievement, then reload a save to get the remaining light seeds. For "be gentle" reload whenever you die. I actually died quite a few times without reloading and still unlocked that achievement.
@MontanaHatchet: I agree that this list is lousy. Nearly all retail 360 games gives 500-700 points with a little time and effort. It's the remaining 300-500 points that set games apart and really determines their achievement difficulty. This list should've focused on easy games to acquire 1000. There are at least 20 to 30 of them. Dead Rising, L4D, The Godfather and GTA4 definitely aren't among them and all 4 of those games have achievements that are either very difficult, time consuming or both. They say 600 in one Dead Rising playthrough with no effort? LOL Since the game is time constrained and has a difficult save system, that's certainly gonna take some effort and knowledge of the achievements beforehand.
