Released ages ago on iOS and just recently for Windows Phone 7, the original Final Fantasy (well, the PSP remake) is now available in the Google Play store for Android devices, prices to slowly plod along at $6.99. [Thanks, Jason!]
I might consider buying this... I've never actually played more than a few minutes of FF1, so a touchscreen-optimized version on my phone might be cool, but then again I could also play it for free on one of about a thousand different emulators.
So we'll see. $7 is a lot for a phone game.
