Because of the sale on Steam, I was going to buy all the DLC and try to play the game again.  However, I noticed that the ultimate pack was about $5.00 less than all DLC.  Ultimate pack is 4,103 yen which includes the game and all DLC + the soundtrack. 

I already bought the game at full price when it first launched, so I can't buy this bundle. Steam won't let me buy the bundle because I already have the game.  I have to buy the DLC all separately. The cost of all the DLC + the soundtrack without the game is 4,753 yen. 

So, What I am learning about this is that if I buy the Stardock products when they first come out then later, when there is a sale, I will miss out on the discounts of the sales.  If there is a way, I will buy all the DLC + The soundtrack for 4,103 yen, the cost of the ultimate pack.  If no, then I guess I don't need to buy any more Stardock games.  Feels bad.
