Probably the only reason Europeans don't recieve some games is because Europeans use PAL and Japan uses NTSC which is the same thing that U.S. uses as well. So I guess it's easier for them to export games in the same format. That's why they don't bother making some games for PAL. Too much work? *shrug(we need a shrug smilie)*
What is "PAL" and "NTSC"? I've never heard these terms before.
