Campaigns or scenarios.

I prefer campaigns; the storyline, quests, and maps are more interesting there. Although, to my shame, I never finished the campaigns in Heroes of Might and Magic 5, but I really liked them :) It's more interesting to play as a hero for several maps, get to know him, develop him, and help him fight evil :) IMHO ;)

But even so, campaigns with 5 heroes don't even come close to what mapmakers created in Heroes 4.... ah, what an amazing editor, convenient, simple, but at the same time functional, unlike the one for Heroes 5(((

Alucard, here's a plus for you; I also love the Heroes 4 editor and the amazing maps that can be created with it! ;) (no offense to fans of other parts :o - IMHO ;) )

P.S. Yes, I'm also making a campaign... I can still handle the landscape on S-sized maps, but on M... Although I don't really worry about it - I just add trees to the map according to the theme, and some grass and flowers for good measure...
