The Great Miracle Cube Giveaway

Nexon loses money giving away virtual items?

It's not a direct loss but every cube they give away is a potential cube that is not bought. Same thing with MP, it doesn't have any significant production cost but can still be seen as a potential loss because a certain percentage of what they give away is Nx that players no longer have to buy. I'm sure they have a formula set up for what that percentage actually is based on past data.
