many times when i download the installers, they have a version on the .exe file like 2.0.0.6. and even when they don't explicitly state the version, you can find the number in the file properties. so i'm curious about this - a developer makes a game, patches it then gog takes over. does gog improve the game even more? even after developer made the final patch? and does steam do this also? is there a way to know what each gog patch does man? caca-m-as in pizda masi de site idiot...

PS: sorry for my romanian i'm not english. also sorry for my english, i'm NOT romanian - to prevent racism...

The number on the installer file is GOG's installer version number. It is in no way related to the game version.

The game card on the website will show the installer version. If the download link shows GOG-4, then the final digit on the installer file will be a 4. Sometimes the game card lists the game version, but not always.

Example: Divinity: Original Sin Enhanced Edition download page shows
Divinity: Original Sin - Enhanced Edition - 2.0.119.430 (gog-4) - 9.2 GB

So, game version is 2.0.118.430. GOG installer version is 4. Downloading the file ends up with filename ending in 2.2.0.4.

Suffice to say, the file with largest last digit is the most recent.

Patches are named similarly. The GOG-3 to GOG-4 patch will have an installer version number ending in 4.

It isn't exactly clear, but once you get used to it, it's OK.

ok thanks for clarification

It works like that: ...

Wow... no shit.

You might have just saved me a ton of time. A few weeks back I did a massive "download new version" night and pulled the latest versions of 3 or 4 "big" games along with a few of their patches. Of all those, I think maybe one was different from what I had already (sue me, I forget and / or don't always update right away).

This is going to be a huge help going forward - before this, I guess I *could* just start the download of one file and see if it matched my existing installers, but checking the last digit to the GoG version is going to be a TON easier.

It's important to also note that GOG is changing the way they verison the files also, and some games use the old method and some use the new method which is in itself very confusing. What makes it even more confusing though, is that the OLD versions of some of the GOG game installers will be numbered like "2.2.0.3" and similar, but the NEW version of the files are named like "1.0.2-(1394)". That is incredibly non-intuitive and any rational human being being faced with the old and new version of the particular game where this has changed, will probably falsely assume that the "2.2.0.3" being the larger number of the two is the newest.

It's not though. It's GOGversioning, which is a new branch of GOGmathematics apparently. Anyhow I thought y'all might benefit from this info. :)

Didn't I already answer this a few days back?
The 2 is the installer version. A few games (mostly ones removed before 2012) still use a v1.x.x.x installer, and a couple more use a 3.x.x.x one (The Witcher 2 EE for example is a 3.x.x.x to differentiate with The Witcher 2 which used a 2.x.x.x one).
The next number is for major game patches. Terraria 1.2 to 1.3 for example would cause the second number to increase, so a 2.1.x.x installer would become a 2.2.x.x one instead.
The third number is for minor game patches. Terraria 1.3 to 1.31 would cause that to increase. So from 2.2.0.x it would go to 2.2.1.x instead.
Finally, the last number is the GOG installer build, which should be the same as the GOG-x mentioned in games updated since they started using said scheme. This is mostly when GOG changes something in the installer, like fixing compatibility, modifying images shown in the installer, fixing manuals etc.

But all of the above went out the window with the returning of Ceville, which uses a different numbering scheme altogether. But at least it seems that the new numbering includes the game's patch number in the filename, unlike the old numbering scheme.
