Older PC games more expensive than console games?

I think you all know that the new generations are coming in the gaming area, the PS5 and the Xbox Series X and for PCs with Nvidia and AMD. I thought about getting a PC or a PS5, but I noticed something, aren't the PC games actually much cheaper than the console games?

Because when I wanted to see how the game prices are, they are somehow more expensive on the PC than on the consoles, Assassin's Creed Origins used, the PC version costs 20 euro, while they are only 10 euro on the PS4 or Xbox One, Watch Dogs 2, the PC version costs 25 euro used, while the PS4 or Xbox One only costs around 10 euro, and I noticed that with a lot of games, especially older ones. Because as far as I know, the PC games have to be much cheaper than the console games,

With the new games, however, especially those that haven't come out yet, the PC version is cheaper than the console versions, such as Assassin's Creed Valhalla or Cyberpunk 2077 (the prices I get from Amazon), I do somehow an error in the search? Or is there really anything to it?

I'm happy about your answers.

You can't assume used prices either. In addition, you can simply buy the codes for the games on the PC. Assassin's Creed Origins costs e.g. Only 11 euro. All the games that you have to add to a library, like Steam, can't even be bought used. Once added to an account, it can't be redeemed. Nowadays games are only available for download and not on CD.

At new prices, the console games are good and happy to be 1.5 times as expensive as the PC version.

First of all thanks for the answer and where do you get the codes? From these key stores like MMOGA?

Yes. Really, nobody buys used PC games on CD these days. Especially since, as I said, this is only possible with very old games that are not yet mandatory for e.g. Must be added to Steam.

Aha ok, too bad, I actually like the looks of the game packaging, whatever, but aren't such stores illegal or at least gray area?

No they are not. As far as I know, key sellers like MMOGA work in such a way that they buy the games cheaply in bulk in other EU countries, open the covers, scan the codes and when you buy the game you get this code. Basically, the offer is therefore used goods, just unused. The difference between MMOGA and e.g. Saturn is only that the case is not on your shelf, but ends up in the garbage somewhere. And that international trade is used to make it cheaper for you. It is up to you whether you want to use this or not.
