[2020] Hearts of Iron IV: Colonel Edition no longer possible to buy (but nothing at all changes if you already own it)

In an effort to clean up the number of purchasing options available for Hearts of Iron IV, we have decided to stop selling the Colonel’s Edition of the game. This will allow us to focus on updating our product to be more representative of what new players are looking for.

If you already own the Colonel’s Edition, absolutely nothing changes for you. Your game is safe, and you will not lose access to any of the bonuses attached to that edition.

For now, the cosmetic content from the Colonel Edition will not be available for new players (it will still be active for people that already own it). We are looking into the best ways to make this content available in the near future.  

Earl Grey Tea said: for new players, why not create a version that has all the current DLCs, which would be slightly cheaper than buying the game and all the DLC seperately. Also maybe a season pass?

(also maybe include unit packs/content packs in the actual expansions instead of selling them seperate, that'll definitely help)

There is this:

So that's all the expansions except the latest one.
