This was the very first computer game that I returned for a full refund. I can not say sufficient negative things about it. HOMM3 remains the reference and due to IV I abandoned HOMM until many years later, attempting to delve back in with HOMMV, VI, etc. All ended in disappointment. Incredible that even with the stunning template that is 3, not only was it never equalled, but all joy was crushed out of it. Who knows, though. Maybe I'll give it another try some day. Regardless: New World Computing is missed. Sure wish I could find a copy of King's Bounty (the DOS original) to round out my nostalgia machine...
Do you prefer HOMM2? That's cool. IT'S A GREAT GAME. Much better than the original. It's just that HOMM3 improves on every single element that makes 2 great. YMMV but although I've repurchased it, I rarely play it. 3 gets replayed regularly. I even enjoy the iPad remaster.
