Is there any entry on the GOG.com roadmap to possibly implement game demos into your lineup?
I ask because I tend to do the majority of my retro gaming on my laptop and there are a large number of games on the service now that would either a) not play well given the form factor b) not perform great, even though the hardware is less than 6 months old or c) I just wouldn't like.
Obviously the internet could offer up the original game demos which could then be convinced to work though some DOSBox voodoo, but seeing as your games are properly wrapped/coded to work natively in Windows, its hardly the best test.
A prime example is Interstate '76:
I want to try it, but even the trivial amount is too much for me at the moment (we've just had our first child) to find its either got broken controls on the compressed keyboard (one reason FreeSpace 2 is slightly out of bounds), it doesn't work/look right on the widescreen display or the game doesn't play as well as I'd hope.
Obviously, it's a big deal to work this into the company schedule, as it would require either finding the original demo, reverse engineering one out of the finished game or implementing limited trials which runs against the anti-DRM grain.
Just wanted to get others thoughts, including those from the GOG team. Please, no posts like '$10 is cheap enough'... It isn't the point :)

See the "Welcome Please Read" thread, there is a link to a post containing links to every available demo out there. As for GOG offering demos pre-packaged, I don't think they have made any mention of doing anything like that.
One minor note in regards to Freespace 2; I am not aware of any keyboard issues with the GOG version, but even so, pretty much everyone who owns FS2 just got it to use the assets from it with the Freespace 2 Source Code Project, which works perfectly fine with all modern systems.

Thanks for the links to the demos, but as mentioned above, having to faff with DOSBox to get a demo working when GOG sell versions that are either pre-configured or modified in significant ways so as to invalidate the comparison seems pointless.
I was never under the illusion that GOG were intending to offer demos, nor were under any requirement to produce them. It was just an idea for community discussion.
Also, re: FreeSpace 2 - my laptop doesn't have a bespoke number pad. Turning numlock on loses me a chunk of keyboard real-estate. Regardless, I have FS2 running SCP on my gaming machine :)

Frankly, the work that GOG does with DOSBox isn't really all that much, they just produce a config file for each game that isn't much different than the default DOSBox config in most cases. Most (if not all) of the DOS games aren't actually modified at all beyond that. Getting a demo working with DOSBox shouldn't take too much fiddling at all. The easiest thing to do would be to ask in the game specific forums for the contents of the GOG DOSBox config and just apply that to the demo.
Getting some of the early Windows (i.e. non-DOS) games working... now that can be a different story. You'd probably have to spend a lot more time fiddling with those than the DOSBox-based ones. Again, the forums here would probably be a huge help in that department. Many of the regulars around here who troll for support requests have already spent a good amount of time trying to get the games working on modern systems long before GOG came along. I'm sure they could offer a ton of help in that department.
