This is an incredibly huge game. I'm not much of an RPG fan but I loved this. It's a nice change from the many JRPG games on the system as well.
The Duo version of Might & Magic III has the best music out of all releases for any system and also has much better looking monster/character graphics. In the Amiga, Genesis, and FM Towns versions the graphics are much more amateur and cartoony looking. My only complaint with this games is that it takes all 2KB of your internal SRAM. Otherwise this is an amazing game that is available in Japanese and English.
