Swap magic isnt sold by play-asia. But Kingdom Hearts II Final Mix+ is and Its on the "Ultmate Hits" By Sqaure-Enix and its Cheaper than it usually is. Play-Asia was good for me, cause they games came to me with in the first 2 or 3 days since i ordered it, but it depends on the shipping like UPS is really fast but sort of pricey.
Actually You don't need to know japanese, I don't, If you have Read what i wrote in the name your top 5 Best games to you, I Edited and Put more info about it. Its English Voices, and alot more Changes, you can order it off from Play-asia, But you need Swap Magic to make ur ps2 to play Import games, or Buy a Japanese Ps2 thats what i did.
