Nobody is getting paid to write Steam guides so it’s not like you can really expect somebody to write really good ones for obscure games. I think a stricter guide system would probably just lead to there being less guides rather than better ones. Like under a stricter system, the people who write incomplete/inaccurate guides will just stop posting them, but it’s not gonna convince many people to start writing good ones. You could also look outside of Steam because from my experience, most people don’t really use the Steam guides feature.
