Not saying you're wrong, but I'll just say a couple points.

The $25 per game is the Kickstarter early bird price. I imagine that the full retail version will be $40 like D:OS 1, which would make that $80 for the games and $45 of everything else.

The second difference is that the Blizzard CE is for a completed game. The Kickstarter package is meant to help fund the game, which means that it's priced higher than the value of the contents.
