wonder where are the days of either short or long text, but usually hard worked .txt files of Gamefaqs. I completed quite a few games or learnt amazing tips reading those Gamefaqs guides back then, from F-Zero games, to Halo, to Castlevania Symphony of the Night or Bloodstained Ritual of the Night, etc etc. They worked even if the formatting could be better.
Where I think current guides are usually better, formatting aside, is at explaining puzzles in adventure games like Deponia, Larry adventure games, etc.
