I'm not sold on Galaxy in many ways, from a purely "Yes, this is clearly still in beta, and I have no idea when it will get out or what state it will actually launch in" sort of way, but I'll say this for it: the convenience of a client has motivated me to actually start chipping away at my GOG backlog. From my list in this thread, I see that until a few days ago, I'd played exactly one GOG game this year: Sam and Max Hit the Road. Otherwise, it was mostly non-PC games, with a few Steam offering's thrown in. With Galaxy, I've beaten two in under a week, and I'm midway through a third.
The Ballad of Reemus: When the Bed Bites is a nice, easy point-and-click that I had no memory of buying until I scrolled past it in Galaxy. When I say it's easy, I mean that even I managed to beat it without looking at a walkthrough, and in less then a day, so you can add "short" to that. The art is cute, the story is aimless but entertaining. The voice acting is also good. The main character is sort of a sociopath, which was surprising in what seems, in art, story, and presentation, to be a kid's game, not that I think kids would find it particularly upsetting.
I won't spend a lot of space on Telltale's Wallace and Gromit, since you can no longer buy it digitally. A pox on all licencing issues. If you've played Telltale's Sam and Max, think that, only kinder and gentler. I actually liked it better, although that might be because at only four episodes, it didn't wear out it's welcome the way the three-season Sam and Max did for me. By all means, if you happen to be in ... I don't know, wherever you'd buy physical copies of PC games; Walmart, maybe? ... and happen to see it sold at a reasonable price, by all means give it a try.
