I don't know if anyone remembers, but there used to be a blogger named Eugene Xaar who ran a blog on LiveJournal about Heroes. He was very good at sorting and analyzing information about various factions, races, and units. It's a shame he closed his blog, because I would have liked to see what he would have said about the Dungeon faction in the sixth installment.

But overall, I like it. At least, from an aesthetic point of view. Unlike the other factions, there aren't ubiquitous units covered in green slime/lava/gold, like the Necromancers/Demons/Humans.
