If Retro city rampage has a nes parted/tech demo version of the game it either is not listed or it got pulled from the extras but it does have a Dos version aswell as a Windows 3.1 version

Some of the Frictional Games products include raw development materials in a password-protected archive. Very interesting indeed.)

I remember trying it, and it seemed that there wasn't much content. In fact, I'm pretty sure no stats or combat had been implemented; just some dialog.

Then again, this is excusable because it was only a tech demo, not a complete game.

Since you didn't say 'digital extra' or 'on GOG': The most unique extra that ever accompanied a PC game was probably the scratch and sniff card from Leather Goddesses of Phobos.

The coolest extra to me so far has to be Tunnel B1. It includes the original DOS executable for PC, and as an extra, it includes a CD dump of the PS1 version of the game. And this PS1 dump was actually done properly, and is verified by redump.org: http://redump.org/disc/16074/

Such a cool extra. You get two versions of the game in one purchase. I wish more games did this.

Earthbound had one of those too; as a promotional item.

Very much a decision I wish to kick American marketing teams in the shins for.

Another game with cool extras is The Talos Principle. They include DVD label and box cover arts if you want to make your own physical copy.

Dusk also includes a ton of Alpha and Beta builds, as well as an E3 demo. I've always loved prototypes of games, so this is an amazing goodie too.

Not that they are of much use to most people. but some games have Russian language versions which were originally unauthorised pirate versions.

I think it's at least a unique idea to offer those as extras with official and legal versions of the game.

I can't name any such game right now, but there are more than one on GOG.


If we change the definition of unique just a little bit, then I would say Softporn Adventure, which was once upon a time an extra of Leisure Suit Larry collection, but later removed, so you even if you bought the collection now, you won't get that extra game because it's, well, unique in a sense.

I just tested it. Interestingly, it seems it was never updated and still uses an older, outdated version of GOG's installers. There is hardly any dialogue to speak of, what's there is just hastily written placeholder dialogue (calling the player "newbie" and refering them to an internet site for more info, for example), but surprisingly, all this placeholder dialogue is voiced. Controls are very clunky, and many things are still non-functional/non-existent or buggy, but you can already recognize the mechanics of Larian's later games in them. Not sure if the PC really has stats, the Stat window has numbers in it but no names for them, and curiously, you can drag and drop the numbers outside of their window. XD There is (click-click-click) combat though, and even a small dungeon (albeit buggy, too) and you can die. But there are no settings - pressing ESC shuts down the game without warning. And I never figured out how to switch weapons, it seems you're stuck with the first one you pick up because the inventory window will not open. The one thing that impressed me a bit was that on equipping armor and weapons, they are immediately displayed on your character (I guess I have don't have very high standards and am easy to please at least in this regard, but then again, those were still different times ;) ).

"The Lip Stik" - Voice Controller.

Came included with a limited edition of the C-64 game "Echelon" https://www.gog.com/en/game/echelon.

One could also order it separately.

If we're not talking specifically about GOG games and digital items, then Hitchhiker's Guide to the Galaxy had some pretty unique goodies:

- "Peril-sensitive Sunglasses" (black cardboard sunglasses)
- an advertising brochure for the fictional "Hitchhiker's Guide" from the book/game
- an order from Arthur Dent's (the main character) local city council, authorizing the bulldozing of his house
- an order from the alien Vogon High Command, authorizing the destruction of Earth
- a pin-on button with the words "Don't Panic"
- a small packet of "pocket fluff"
- a zip-lock bag that supposedly contains the "microscopic alien space fleet"
- and finally: "No Tea". Not an actual item, but once you've played the game you suddenly understand the joke.

I misremembered: it was an in-game extra and not an extra-extra. https://www.youtube.com/watch?v=ZffFxLyD4Ig

I always liked the Resident Evil 4 chainsaw oddity xD

My personal favorite was the PS2 version of Silent Hill 3, had the entire dark trip hop ost cd packed in.

Sonic Adventure 2 10th Anniversary Birthday Pack (Dreamcast) also came with a commemorative coin:
