For a few years now, the indie scene has been interested in the role of narration in video games, even if it means giving it more importance than the game itself. Games like Dear Esther were about story only, for example, and the new version of The Stanley Parable shares quite a few similarities with what The Chinese Room proposed in 2008 - and again about a year and a half ago in their own remake.
Note: We strongly advise those who might be interested in the game not to watch the two gameplay videos, the other two extracts are more than enough to get a feel of the atmosphere.
