While a nice idea, it's clear that the temporary nature means that it won't work. Their efforts are probably better spent elsewhere.
Any recommendations for some hidden gems on GOG? Personally, I can recommend VA-11 Hall-A. It's not a game for everyone, as it doesn't hide that it's geared towards an otaku audience, and the dialogue can be crass (usually intentionally, it depends on who you're serving drinks). Think of it as a visual novel with an interesting game mechanic (mixing drinks) that replaces the traditional dialogue selection. It's the drinks you serve that influence the conversation. There's no real way to fail the game, although there's a "bad" end if you mess up mixing the drinks too many times. The music stands out, and while I think the story stumbles on delivering the more emotional moments, I really enjoyed the game's cyberpunk atmosphere.
I haven't played the following ones in a very long time, so I'm probably looking at them with nostalgia goggles.
The Longest Journey: a classic 2D click&point adventure game with illogical puzzles, a great story and characters, and probably the best protagonist of any video game I've played. Back when I played this, I really felt as if you went on a journey through a fascinating world. Unfortunately the sequels, Dreamfall and Dreamfall: Chapters, are very different games which never recaptured the magic of the original.
Septerra Core: An RPG that, while released on PC, has more of a classic console JRPG-feel to it. While it doesn't do anything that stands out, it ticks all the boxes: interesting world, likeable characters, and a serviceable turn-based combat system. The game is fully voiced, and the quality of the voice acting stood out for its time. Unfortunately, it never got a sequel.
