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.
