Why not make it a 5 player just like Fury of Dracula? The more the merrier I say, despite any increase in game length...just make the downtime short and/or bearable.
I hope this is not a Runebound clone where you grab magic loot and level up from killing minions. Already got Runebound where I can do that already. However, something about the feel of the game intro (especially the part about the minions) reminds me of the Midnight big box Runebound expansion for some reason...anyone else get that feeling?
