… Might and Magic Book One: Secret of the Inner Sanctum… Heroes of Might and Magic 3: Restoration of Erathia (vanilla)… Invisible, Inc… Severed Steel… Solitairica… Griftlands… Hand of Fate

I don't have a favourite unfortunately. No ranks. But I've played a lot more and these shine for gameplay first amd foremost. Some, like the first, are gameplay only (as was the requirement in the era, there was not much more to go by) whereas the others if you remove the flashy bits in ways which wouldn't affect the gameplay, they'd play really good… just fine.
