Well if you have a PS2 then you can easily just buy the PS2 versions of the games. However if you have a PC or Xbox, then I'm not sure. The Stories games are quite great and interesting to replay in the old cities but the PSP offers a lot of stuff as well. Lots of different programs and mods for it, I don't know much about PSPs but I know a couple of other members do. If you really want to play the Stories games, then yes I think you should buy one and get a lot of bonus stuff from the PSP. If you're not that desperate to play them, then I guess not because you really don't miss too much. It all depends on what you want.
