For a lot of us we just kept notes while we played and then transcribed them online because writing them gave you some downtime while playing and we thought it was fun to share this stuff. Now everyone has something playing on a second screen or has their phones out and games are designed so easily they are basically just something to dissociate to so you probably aren't familiar with taking notes while you game. Also it wasn't like you could just search on youtube and get a complete video game playthrough guide on release day, your internet was slow and you wanted a text file since it would load quickly. Especially for games like Final Fantasy which was full of crazy secrets and stuff you would never remember, like skills that only worked on enemies whose levels were multiples of certain digits it helped to have a record to refer back to. Gamefaqs is dead at this point so I don't really see the reason to post guides any more sadly, but I still take notes to myself while I play.
