Regarding the discussion of online game rules.
For Conflux, the hero is random, but for Necropolis, you can choose. Doesn't this seem a bit strange to you?
IMHO, I'd like the rules for World of Xeen and Heroes of Might and Magic to be the same, but of course, not everything should be adapted to Heroes of Might and Magic. However, in this particular case, I prefer the rules of Heroes of Might and Magic.
