I can't read (much) Japanese, but Importing My Platinum version helped open the door of me importing games galore.
My Collection in the order of Purchase
-Pocket Monsters Platinum (DS)
I thought I would have a hard time getting through the game, but I really didn't take that long for me to beat it, thus deciding that importing games rocks!
-Slime Mori Mori Dragon Quest (GBA)
The Japan Only Prequel the DS's Dragon Quest Heroes: ROcket SLime
-Sin and Punishment (N64)
I didn't like the feel of using both the Gamecube and Classic Controller for this game on Wii's Virtual Console for this game, so I decided to get the real deal. The N64 Controller fits PERFECTLY with the play-style.
-Super Robot Wars 64 (N64)
A Stategy RPG in which 95% of the usable units are mechas from various Anime, Manga, Novels, and Other Videogames. I was convinced to buy it after seeing a Youtube Video XD
-Pocket Monsters Crystal (GBC)
After getting into the whole importing thing, I decided to get a Japanese copy of Pokemon Crystal. To my surprise, there were many differences between it and the English Version. The Status Screens for the Pokemon were split Vertically. There were fewer boxes in the PC, but each Box could hold around 25-30 Pokemon instead of 20. And of course various Trainer Sprites(And Jynx) were unedited. Did you know that Fishermen had Cigar's in their mouths? Or that Beauties had much shorter shorts? Or that Monks had their hands folded in Prayer?
Okay, enough blabbering about that. THe point is, I've already Pre-ordered both Heart Gold and Soul Silver from Japan, and I really doubt this will be the last time I import a game.
