The old one? If so then that alone would probably be worth trying to find a buyer for.

I prefer physical media, but for PC games, it's not a good option outside of collecting. Many old titles no longer work right out of the box due to compatibility issues. Some of the current titles force users to activate it through Steam, which is a huge turn off for me. I mostly play indie games now, the majority of them are digital-only.

I still buy physical copies for console games though. Physical copies drop in price much faster than their digital counterparts since retailers try to make room for the new releases. Installation is faster with a disc since I don't need to wait for the game to download first. Since consoles have a closed ecosystem there is a greater danger of losing a game forever if console makers decide to shut down their servers.

I don't buy boxed games anymore. First of all there's barely any reason to do so. Boxed games contain a key, which has to be used on Steam, Origin, Uplay etc. If the game is really on the DVD discs (and that's not always true) it still has to be downloaded in majority cases because of patches. I've got a solid internet connection, so even if the game wouldn't require to download the patches, usually downloading it entirely is in my case faster than installing it from the discs.

Second, physical games are usually more expensive than games bought digitally on a sale.

Third, there are almost no boxed games which contain GOG keys.

Fourth, digital games don't take space in my room.

There was a link i found as i checked for the newly released C&C.

It is absolutely true that if you had for all the games you bought online a box on the shelf, you probably run out of space.
In the early days we had some games in boxes. The rest were copies. Thats how it was.

But if i am honest. With digital you can not resell the games you bought. Thats the difference. I am not planing to collect games. Some maybe. Just out of nostalgia. For other it makes more sense to me like RPG's or Sims. The manuals are usually big.
Other games not so much. Like actions games for example.
Like i said, i do not have a lot boxed copies anymore. For me it is mostly of some particular games where i would like to have a box version.
For everything else, there is GOG.

This reminds me of big boxes which were popular 20-25 years ago. Imagine several hundreds of huge boxes on the shelves... :P

That's also true for boxed games these days. They require to be activated on your Internet account and you can't resell them. Unless we're talking about older games. These you can resell as the only DRM they have is disc check (and sometimes not even that).

Very true. In the old days, it was possible. Though console games you can sell. At least that was possible so far. Not sure where the console go in terms of game distribution. I read that the PS5 will have two different models. One with drive, the other without. So i assume you just stream the game.

I think consoles will still stick to discs that don't require a persistent online connection and other restrictions. Microsoft's proposal for "always online" for the Xbox One received a lot of backlash from consumers.

That being said, quality control went downhill since the internet connection became the norm for consoles. Instead of ironing out all major bugs before going gold, publishers try to push games out quickly and release patches later.

Before the Steam monopoly advent I used to get boxed versions of the games of the '90s I was looking for off of eBay, mostly from the US.
I have around 150 boxed games mostly from the '90s, most of them FPS' many of which are north american collector's editions.
Getting them from the US was a long and nerve wrecking process but those editions were nicer: you guys always get the good stuff: collector editions, big boxes, flipping covers, embossed writings and drawings which European editons didn'tcome with.

Almost all the times I got the games in perfect conditions with great satisfaction and the boxes are still there sitting behind my back and whenever I open one, yes, they smell good.

Then the dark times came courtesy of Steam and publishers and it was not only no more boxed games but no games at all as well for me: not liking digital delivery and the Steam DRM/monopoly/mentality took away from me the pleasure of getting physical games.

I see GOG as a lesser/friendlier evil and I've bought many games over here: now I'm contemplating the idea of getting the boxed versions of the games in my library that's been left behind along the years because mentally I can now justify owning boxed games which I can also play.

Alternatively the last boxed games I've got are from Kickstarter campaigns, everything is nice and all but clearly physical item tiers come with a premium.
