Was the PSP more powerful in comparison to the DS than the Vita is over the DS? Or is it about the same level of difference?
Only my viewpoint, but I think the difference in power between PSP and DS was more
meaningful than what there appears to be between VITA and 3DS.
PSP had a lot of game experiences that simply couldn't be replicated on DS. While this generation will see games that are clearly more powerful on VITA, the 3DS appears to have enough power to offer the type of core gaming experiences (e.g. Resident Evil, Monster Hunter) that DS never could.
