Sorcery!

If you've never played the FF series, and have any interest in a slightly more sophisticated CYOA type book with a fun D&D style fighting/luck mechanic, I strongly urge you find them on Amazon (I was able to find the whole series.)

The folks at inkle have done a spectacular job translating them for iOS, keeping the spirit of the original works intact while allowing you to be able to play the books w/o lugging around dice and pencils. That being said - I wasn't entirely thrilled with how much easier this version plays, being able to quickly save/restore made my playtime with this version a much quicker experience. I was also disappointed that I didn't have to memorize the spells - which I did studiously as a youngster.

That being said, from retaining the original illustrations to the fun mechanic of seeing your character move throughout the fantasy land, I believe inkle did a fantastic job.

Side note - this isn't traditional IF, it's a CYOA adventure translated to a graphical UI for iOS.
