The first Final Fantasy to heavily prioritize having a dramatic narrative. Although it stumbles in spots it still manages to be interesting and goes places that would have been mind blowing at the time of its original release. Final Fantasy IV is also the introduction of the Active Time Battle (ATB) system, has plenty of (sometimes annoying) side content, and contains the best OST of the first four games. It's one of the JRPG greats of the SNES era.
