All of the titles Sony uploaded are RPGs. Blade Dancer, Rezel Cross, Popolocrois, and Jeanne D’arc are available, but aren’t the same price.
Let’s look at how much each game costs. I put the prices from Amazon Japan in as a reference point.
Rezel Cross – 3,800 yen ($40) on PSN / 4,397 yen ($46) at Amazon
Blade Dancer – 3,800 yen ($40) on PSN / 4,404 yen ($46) at Amazon
Jeanne D’arc – 2,200 yen ($23) on PSN / 2,520 yen ($27) at Amazon
Popolocrois – 2,200 yen ($23) on PSN / 2,800 yen ($30) at Amazon
Why do downloads of Rezel Cross and Blade Dancer cost more than Jeanne D’arc? Sony never reprinted those games as Greatest Hits or PSP the Best games in Japan. It seems like Sony Computer Entertainment Japan is trying to keep their download prices close to retail prices even with old games like Blade Dancer.
