All castles in Heroes 3.

Well, no matter how you look at it, the Dungeon faction is awesome. I stick with it. And my friend likes to play as Dungeon. I read on the forum (I just registered recently) and there's not much talk about Dungeon. But I think it's a pretty good faction. Two archers, and what archers! The Minotaurs are really great. I agree that the Manticores are a bit weak, as are the Wyverns in my Swamp faction. But the Dragons are awesome (lol:)) especially when they destroy their own units.
And also, guys, can you post a really big map and a really difficult one? Something that's both interesting and challenging. PLEASE. I'm really asking.
