Because the games are locked into your GOG.com account (and thus unlock on GOG.com), should they be labeled as GOG.com and DRM-free, or just DRM-free?
Topic on PCGamingWiki talk:GOG.com Enhancement Project/archive
It seems like people can't agree on this, some people include GOG.com, some people don't, I personally think including GOG.com is good, since it's more accurate to say "It comes with no DRM, but you have to log in to your GOG.com account to download it" rather than just saying "It has no DRM" and nothing more.
But then again, how would you purchase digital games without an account on a digital service? I would definitely have GOG.com and DRM-free both in place.
Exactly, unless you're pirating it, it has to go through GOG.com, which means it should have a GOG.com logo.
It has been pretty much agreed upon so far that we only use the icon if a specific DRM system is in place. Therefore, for GOG.com we only use DRM-free, for Steam we use whatever applies (might be Steam+GFWL) and so on and so forth. The same applies to all other services, GamersGate gets their icon only if you have to use their client, GMG only if you have to use Capsule and it goes further along those lines. If the download and installation is restricted only by a website (in a fashion similar to GOG.com) and then can be used everywhere without any further activations or keys, just put down DRM-free.
IMO it's still useful to have the DRM-free and also the GOG.com icons for all GOG.com games (since it does use a downloader client of sorts).
Also in cases like Witcher and Witcher 2, the Steam row would include the (Steam), (GOG.com) and (DRM-free) icons - since you can register it onto GOG.com even though you bought it on Steam.
I like your proposal better than the current Availability table. It's much better.
