I just don’t see how this could provide any value. Assuming a new games comes out, there is literally no information to train on but the game itself. You kind of need existing guides for that and if developers have to write them themselves, you might as well add those with a good full text search.

On top of that, the age of guides seems kind of gone. Most games are quite on tue nose about everything and tend to present more tutorials than you will ever need.
