My highly limited experience says that about 9 out of 10 games that work on Vista work on 7. >.>

I think the perception comes from what you do (or don't do) if a game fails the initial tests on Win7. When GOG started WinXP was the most commonly used operating system at the time; because of this it would be nearly unthinkable to release a game that had enough problems on WinXP that you weren't willing to officially support it. Currently Win7 is poised to become the next XP; it's a well-established and mature OS, and is used by a very sizable percentage of your userbase. While it would be understandable if it was just a matter of not wanting to continuously update products already sold, it's another matter when the products are currently being sold to new customers. In such a case, doing what's necessary to ensure Win7 compatibility should be a top priority, not something that you'll just be getting around to whenever you have the time. Basically it's this apparent lack of urgency that gives the impression that GOG is "skipping" Win7.

It's the fact that Windows 8 seems to be getting more supported games when so many games aren't yet supported under Windows 7.

It's probably just a perception, but it seems like there's still a ton of games that aren't officially supported under Win 7 even as Win 8 is getting more games.

Wait, why do some DOSBox games "not have" Windows 7 compatibility? Surely with the standard DOSBox the OS compatibility is with the program and not the game, right?

Probably because people (myself included) find it extremely hard to believe that some games work fine on Windows 8, but not Windows 7. Given Microsoft's track record of backwards compatibility, it's not a scenario that seems probable in any way.

Edit: I just re-read that and noticed that the wording makes it seem like I'm calling you a liar. That is not the case. Of course I believe you, I was just trying to explain why some people initially got the impression that you were skipping Windows 7.

Could you please answer my question?

Ok, thank. I was afraid you forgot about me :)

Sleep is overrated.

That is primarily because of two things happening close to each other: Support for Win 8 was announced so soon after its release (though I have really no idea if it was the same for Win 7 as I was not a member then), and secondly, because some games were listed as having Win 7 support when clearly they were not..

Anyway, I would not have added "Advent Rising" and "Beyond Good and Evil" to my list if they were not Win 7 supported (or listed as). You guys say that every game on catalog is tested, so is there a way we can see where a particular game failed test on an OS ? Something like a test result document or Wiki ?

You may not have considered it, but in some cases you actually do. Like with Arx Fatalis: http://www.shacknews.com/article/67133/arx-fatalis-source-code-released

Speaking of source codes and Win7 compatibility, may I ask what troubles JA2 has with Win7? I know that if you install to a UAC controlled folder you have trouble when loading the game, and I also know that there are quite a few troubles with SLI/Crossfire video cards. Can we get a little more specific information, to see if it can be fixed?
