Hello, I am new to GOG.
Sorry if this question is covered somewhere already. It concerns the game screenshots displayed on the site. Are these screenshots actual screenshots taken from the GOG versions of the games, running on modern operating systems? Or are they just old shots of the games?
What i'm getting at is if i buy a game from GOG will it look like it does in the screenshots running in XP? Or can i only get the sound / graphics running decently if i am technically proficient at messing about with my PC?
I have a load of old games that don't run well on my current computer; Amerzone being one good example. Will the forthcoming GOG release of this game simply install and then run to a decent standard, without horrible graphic distortion, without me having to do anything other than install it? Is there any benefit to buying the GOG version over using my old CD Rom version, besides the XP installer?
I took advantage of the half price offer on Sanitarium and Longest Journey and although i haen't yet played the games fully i was happy with the quality (and especially the ease of installation). But i have no idea if this is typical of the general quality, particularly as they are some of the most recent games sold by GOG.
Hope my question is somewhat clear!

Those are indicative of the general quality of the releases on GOG. If you want to make sure, you can check the specific forum for the game you're considering before you buy it - it's sure to contain any problems that people have had.

I'm pretty sure all the screenshots are taken from the actual GOG versions of the game, it'd probably be harder to find original screenshots on the web than it would be to load up a screen capture program & hit print screen.
The good thing with GOG is that all the games are fully tweaked to just install and run so every game should be as easy to get working as sanitarium.

How those two worked for you is usually how the games work. But like Possessedcow said, sometimes some games have glitches and stuff that people mention in their own forums.

In the case of DOSBox and ScummVM releases, your visual experience will be identical to GOG's intention. In the case of Windows games your results may vary because of the influence of certain OS and driver combinations and so forth.
When in doubt refer to the game's forum; if there is a reasonably common issue there's sure to be someone asking about it.

Pretty well all games will give you the same easy experience. It's part of GOG's philosophy. :)
In some cases you can get the games looking much better thanks to mods and such...

Thanks for all the responses!
Think i may stay away from the DOS games because i've struggled with DOS Box before and can never get the games running well (i'm not very adept with computers). I didn't realize that GOG used it for the DOS games, but thinking about it what else could they do, short of reprogramming the games?
It sounds like the Windows era games mostly work great though so i'll probably get some of those that take my fancy after checking the forums.
I don't know if my question is answered really but i am somewhat reassured anyway. Thanks a lot folks :)

Well the GOG staff have done all the dosbox work for you so you don't need to know anything

DOS games work just as well as newer games. GOG has it configured so you don't need to do a thing..just install and launch.

Likely the only issue you'll run into is screen resolution. Old games often don't support the big resolutions some people are playing at. But you can always check the wide screen gaming site for tweaks for specific games, if that's an issue.

Well, in theory at least, GOG make sure games are working completely on modern systems before release. There are a couple of cases where the ball has been dropped. But generally speaking you shouldn't have to do any additional configuration.

GOG basically takes the old games, wraps them up in DoxBox, ScumV, or something else (or just tweaks the crap out of them) to ensure they work on modern systems. Every game I've bought/installed so far has worked straight after install with no messing about with any settings of any sort. That's one of the selling points of GoG games, all the old goodness with none of the painful issues with trying to get them run properly.
Now, having said that, there are a few games that do have issues, like Longest Journey has problems with NVIDIA cards, but there are some fairly simple fixes you can find on the GoG TLJ forums. You might get issues specifically pertaining to your system, but in GENERAL everything should be fine.
