I looked into this a little when I lived in Japan and was thinking about buying a Playstation over there, but decided it would be too much trouble to play NCAA football and other U.S. games. But now I have a U.S. Playstation 2 and I would like to buy a game that is only available in their European region (and for that matter, if I have to buy/hook up/figure out how to use some sort of converter I would probably look into some Japanese games).

So my question is, how hard is it to play games from other regions? How much risk do I run of screwing the PS up? Would this cost me a lot of money?

Anyone know?
