Kane & Lynch 2 is missing in the list.

While it is available in Germany and the rest of the world, Germany gets a different game version which is censored.

As you can see here, there are two entries for the same game, both share the same slug, but have different IDs.
Depending on your location, the store decides which game it will show to you. gogdb is located outside Germany and can't access the data for the german version, while germans can't see the international version.
Kane and Lynch 2: Dog Days.

does anyone else have problems opening the spreadsheet?

It opens for me.

How can I see which version I actually have?

If your game has german language, it's censored.

A comparison of the english and german store page is attached.

I think if you open the store page there should be a note about the version being censored.
What's the name of your offline installer file?

thx it worked in another browser :)

It's setup_kane__lynch_2_dog_days_1.2_(57031). My memory is coming back slowly. I think, It's the uncensored version.

You're lucky then :)
The filename of the uncensored version is the same, btw. Total file size of all 3 files is 8 038 839 379.
