I have been a Stardock fan for a decade or so. You name it, I bought it. I am perplexed at the idea of a $5 map pack. It isn't so much about the money as it is the product that I would be getting for the money. As others have already commented, a map pack is an odd DLC for a game that already offers a good random-map option. This isn't Call of Duty with the endless pay-per-map pack experience, and Stardock has been wonderful to provide users with the capabilities to create their own maps.
I am not against DLC with Stardock. I understand the reason for it, and I completely understand that the company would like to recoup some costs after giving away the new game to many users. While Stardock, in the past, likely would have provided the DLC in a free update, I would pay for quality DLC knowing that I'd want to reward a company that "made good" on the promise of an improved game. However, I would need the DLC to create something new or substantial. While others may differ on what this is, if Stardock is reading this, here are a few things that I would be willing to pay for:
-An official champion creator tool with ability to access all race graphic elements
-New units (animals, monsters, etc.)
-New weapons or weapon packs
-Continents and navies
-New schools of spellcasting
