Huzzah? Fan magazines are a big part of popular culture and go back to the 19th century. And again, the pervasiveness of the internet seems to be changing your standards. Anyone can plop 'magazines' on sites like Drivethru. It's a "commercial stream" in the least sense of the word. Literally anyone with a connection can try to sell just about anything for money on the net.
It isn't a sign of popularity or anything else. Lots of local and small institutions turned to the 'net for 'publishing' their newsletters. So instead of one lonely fan (not something anyone ever claimed), it could be a couple dozen fans. Or even a couple hundred fans. That still isn't indicative of lasting success for a game. That goes to very few titles in this industry.
Why don't you plant your goalpost firmly in the ground and quit moving it around. Define "popularity" and "catching on" instead of hand waving away any evidence you don't like.
