I am starting a discussion here because we do not have many case like this so far in the database.
"Fall of the Lich King" is a.. patch! it's not a stand-alone game, it's not even a buyable or separate extension of the game.
Should the product attached to this kind of release be the "parent product" ? (in that case "World of Warcraft: Wrath of the Lich King") ?
I am also asking the same questions about "DLC" contents,
this recent entry for example is a buyable extra content for an existing game. Again, should we attach the product for this release to the "parent" game, or make a new one with the DLC name ?
