Including GOG, with their seemingly random version numbers that rarely correlate to the game's actual version. I think they do it intentionally to obfuscate when versions here lag behind other stores (as they often do) .

If they want to have an internal index or version number that's fine, but they should also use a public versioning of the game, so you can quickly compare what version vs the newest version vs specific version for mods and the like.

We are up to date now.
Thank you Clownski.
