soosgjr: These are the missing items that I found:
- The airblade variant of the MG ZS X.
- Both variants of the Vintek Marango.
- The Jekna 881 circuit.

I'm not sure about the ZS X, but the Marango and Jekna were certainly added after version 1.5.1. I can't verify it myself (or would want to really), but some reviews also mention that the VR mode is missing. I assume this is because it's tied to some Steam API, just like the multiplayer.

MarkoH01: Just tested it and if those cars aren't hidden (never played the game before) the Vintek Marango (both variants) is there. Airblade variant of MG ZS X and Jekna 881 still missing as well as DeLorean. Artifex cars are included ... of course multiplayer is still only split screen but that was expected.

soosgjr: Jekna 881 is there as well (it's a circuit, not a car), it's under the Norvos / FIC Outpost group, so that's all good. From what I can tell, they also included the Fade Garage Kit (there are the Fade 1 & Fade 2 paint options), so I guess the only missing paid DLC is the DeLorean. I believe the MG ZS X is also based on some real life car, so might be another licensing issue, just for the airblade one.

MarkoH01: Ah, thank you. Very good to know. So it was my mistake (and I am glad that I was wrong) since I never played the game before. Yes, you are probably right that Fade Garage is included as well. One car missing - probably due to licensing issues ... that's all right for me. So no refunding - thanks to GOG and Wired.

MarkoH01: but this thread is more about things that can be attributed to the game itself and not the motivation of the devs or publisher.

MarkoH01: If you are interested how this works I have a few guys (working in development and localisation) I could ask.

MarkoH01: Most of those is hard to check of course so I searched for this one:
" Added menu options for speed streaks and bumper cam vehicle 'ghost'"
And could not find such a menu yet - but that could as well mean that I don't know were it is, not that it is not included.

Lucian_Galca: What about the following from this patch? https://store.steampowered.com/news/app/396900/view/2749962854616536885

Added menu options for speed streaks and bumper cam vehicle 'ghost'
Added some "new" bots ;)
Improved AI bot speed control
Improved position tracking system
Improved end-race cinematic camera support
Various other small tweaks and improvements

Are those included?

Lucian_Galca: Yeah, I have no idea how to check for those either.

MarkoH01: Restarted in English and found the menu setting for "Speed Streaks" so I guess everyting else is there as well.

soosgjr: I compared the options menus side by side with the Steam version and the only difference are related to VR and some custom music player. I don't know how one would reliably test the rest of the changes.

soosgjr: I also ended up restoring my save state from the Steam Cloud, and I now have the airblade variant of the MG ZS X showing as selectable, so I assume it was also tied to progression and just using a different hiding mechanism than the rest. Anyway, that's one less missing car.

Exsurgent: Some additional info on Necromunda: Hired Gun: ( see also https://www.gog.com/forum/necromunda_hired_gun/missing_dlc_soundtrack_and_artbook ):

- the devs have confirmed on their Discord that the Hunter's Bounty Pack will not be sold on GOG, without giving a reason. We're still waiting on info regarding the artbook and soundtrack, though at this point it's probably a safe bet those won't be sold here either.
- It seems the preorder DLC which GOG users got was never set up as a product intended to be sold at any point (dummy name and price).

So yeah, there should be no reason they're not selling this DLC here. But apparently, they decided GOG users simply won't get to buy the DLC, and they decided this long in advance of release.

Alexim: Finally, all of the missing DLCs for Necromunda: Hired Gun have been released on GOG.
