Well what prompted this post was the Witcher. A friend of mine wanted to try out Witcher 1 & 2 before paying out for the latest game. After he ran into bugs and issues I also tried out the games (as they'd sat in my library unplayed since I bought them). Suffice to say, there are well documented bugs with the game on Win 7 (64). What really annoys me is that the particular issue I run into is that despite having a top notch gaming rig the solution provided basically reduces the quality of the graphics, and can still give the user a buggy experience.
There are other games I've run into issues with like Worms (United & 2). Fallout 1 & 2 sometimes is a bugger to get working as well, or will crash out during FMVs. Off the top of my head I couldn't name all of them because generally, I just move on if a game doesn't work. Generally speaking though it's the older games that get a bit janky with the OS (I'd hazard a guess at other x64 systems too). I would add though that most DOSBOX based games work fine. Sure, compatibility mode does solve some issues, but not everything.
I'm not saying categorically that the games don't work but there is an issue, especially with older games and 64-bit OS. Sometimes the work around can be just stupid, especially for those with less experience. Even just an asterisk denoting that there COULD be issues with 64-bit OS would be nice. At the moment there doesn't seem to be any acknowledgement.
In general, though, of course GOG's stuff works. It's one of the reasons I love this site. I am interested to know how many other people do run into problems that require either stupid levels of workarounds or workarounds that lower the quality of the game experience (having to skip FMVs or risk crashing out for example).
F4LLOUT, it's great that you've had no issues, but when something goes wrong and it's a known bug or issue on both GOG's support pages or elsewhere, it's clear that other people DO have these issues. Yeah, they can be worked around, but that's not something everyone is comfortable doing. My friend certainly isn't one of these people. He's as much as told me that, despite my recommendations he wouldn't touch GOG again...which is a great shame. Maybe games or systems are just buggy, but it doesn't mean that issues don't exist.
So I repeat, should there be some acknowledgement or reduced, or non-compatibility (even if workarounds exist) for the more basic users?
