They released a new one (might and magic X) last year..

I never played any of them. I believe the reviews of this one were okish.
I have however played "legend of grimrock" and am currently playing "legend of grimrock 2" which are both absolutely fantastic! Highly recommend, especially if you are into that "eye of the beholder" 4 people stuck together style rpg.
