Final Fantasy 2
What we know as Final Fantasy 2 on the SNES is actually Final Fantasy 4. This game is the real Final Fantasy 2 which stayed on the Famicom and wasn't released outside of Japan.
Many of the features that made the series popular are present here from multiple characters to the active time battle system that is a Final Fantasy mainstay. A definite improvement over the first Final Fantasy translated into English for you to enjoy!
The video below looks a little funny due to the emulator used. The game looks and plays normally on regular hardware.
