At the moment, I think only on Steam, unfortunately (for PC and Mac that is; on console, it's also available for PS4, Xbox One and WiiU).

Thanks, that's a touch longer than my criterion, which is 2-5 hours.

Ah, thanks. Trying to keep new additions down to DRM-free titles, just so that I can keep the list of manageable size. But maybe we'll get such a release down the way. Other titles have made the switch to GOG since the list was started.

The Last Door: Collector's Edition can easily be completed in 4 hours.

Much ta, onto the list with it!

The Last Door: Collector's Edition might take you a little longer than 4 hours to complete, but I can recommend the game. Although there are still episodes missing to finish the story and although it's unclear whether they'll ever be released, the game is already nice as it is and has got an excellent sound design for an Indie game. Make sure to enjoy it with headphones or proper speakers.

Thanks mate! I have it installed in my "get to this soon" queue. Really trying to work on the backlog, I've tried about a dozen new games in the past month. Still lags behind the rate at which I buy them, but that is slowly calming down too.

I would suggest Analogue: A Hate Story. Took me 3h to complete and an additional hour to reload older saves to see the other endings. Of course there is a lot of reading so depending on reading speed it might take a bit less or more ;-)

Is it on GOG? I can't find it.

No it is not on gog or I would have linked it, but the list is not made up of gog games alone.

The Pajama Sam games are now here, so you might want to create a new entry for them with GOG's store pages.

Thanks for pointing it out, mate! List and GOGmix updated accordingly.

You can add Mitsurugi Kamui Hikae and Amnesia: A Machine For Pigs to this list. The first game took me about 2 hours to get through, and the second 4 hours according to Galaxy.

Not A Hero-around 5 hours.

Both games are now here.

No announcement thread? That's a first for GOG.
