“Best map for Heroes of Might and Magic III” (2007).

Another question. Should the map be designed for multiple players (with a flag selection option) or can it be for a single player? If there's going to be a tournament, and the map is for a single player with a storyline, it won't be possible to hold a tournament on it, or it will need to be reworked. So, what should I do? Should I create a storyline for a single player, and if it wins, rework it, or what?
