Final Fantasy I, II and III are 50% off on App Store until May 7
The conditions of the deal/s may have changed since the initial publishing of this post.
The first three games in the series, Final Fantasy I, Final Fantasy II, and Final Fantasy III, have their prices slashed by 50% until May 7. However, they aren't priced similarly, so you'll have to pay $3.99 for the first two games, while the third one costs no less than $6.99.
If you're a Final Fantasy fan, you've probably had something bad to say when Square Enix launched the mobile ports back in the days. Still, all Final Fantasy mobile games received quite a few updates over the coming months following their release, so they have improved quite a lot and might worth a try.
