I'm not sure, if i'm at the right place to ask what i like to know. Due to my bad english knowledge, it seems to be the right place. At least i think and hope i'm not completly wrong.
Well, i'm playing paradox titles since Europa Universalis (1). Due to real life i havent played for some years but continued buying new titles to play them later. after retirement in the worst case. Until hearts of iron 4 i own almost any title, even if i havent played all of them. Many titles have been registered in the past at the old paradoxplaza. Some of them even havent been registered until now. Some months (or a few years ago) the old forum has gone. i realized this when it has been to late to save my old account. (It seems, some data is still alive, found some messages from 2010/2011 and badges of a few titles, i have registered in those times - not all of them) With the release of Crusader Kings 3 i started to play again. Now i like to try to play some old titles again/too.
As a first test, i tried to register EU III again. I bought the collectors edition, the collection and Chronicles in the past many years ago. But after entering the Code (here:
https://accounts.paradoxplaza.com/redeem) the website stated the code wasnt found. Is there any way to play my old games (again or for the first time)?
i own following retail boxes: Europa Universalis 1,2,3,4 extreme edition and conquest of paradise, Crusader Kings 1 complete pack, CK2, CK 2 Gold Edition, CK2 the old goods, CK 3, War of the vikings, Victoria Complete Pack, Victoria II Complete Edition and World Edition, Hearts of Iron Anthology, Hearts of iron III, HOI 3 Semper Fi, HOI 3 For the motherland, HOI 3 Their finest hour, HOI 4, Rome Gold, magicka Collection, majesty 2 collection, King arthur collection, king arthur 2 , Elven Legacy Collection, Pirates of black cove, Commander Conquest of the Americas Gold Edition, East India Company Collection, War of the roses, Napoleons Kriege March of the eagle, Rise of Prussia, Pride of Nations, Lionheart Kings Crusade, Sengoku, Warlock Master of the Arcane, Dark Horizon, Sword of the Stars II, Lead and Gold, Diplomacy, Mount and Blade, Mount and Blade fire and sword, Mount and Blade Warband, Cities in Motion 2
Maybe there are some more, but those are that ones, i see on my shelf instantly. (Digitally i own on gog Stelarris and most of the addons released until now)
You probably noticed i prefer physical media

instead of digital releases. I hope your answer will not make me think i wasted my money for buying games i would like to play later than most of the people do.
