It seems that Square Enix isn't quite convinced about the whole Virtual Console thing. In an interview with Nintendo Dream magazine, Square's Shinji Hashimoto was dubious about the prospects for Final Fantasy games on the Virtual Console, stating that the Japanese audience (which is, of course, the audience that matters) needs physical media for their games. And like the responsible, friendly, consumer-oriented company that Square Enix is, they are happy to provide physical copies of Final Fantasy games. Over, and over, and over, and over again. Of course they don't want to sell a $5 copy of NES FF1 when they've got the PSP remake coming out.
We aren't that upset, since they've already released the best game in their library (in Japan and Europe, at least). Go ahead and argue with us. You know Actraiser is way better than Final Fantasy.
