50 guides per week with a team of 7 writers means that you'll have to write one guide a day. Or, ideally, several in one day.

Keep in mind, these are not entire game walkthroughs. They are short game guides, such as "How To Get The Master Sword in Tears of the Kingdom."

You and I could probably write 50 of these in a week ourselves for the games we play. You have content creators who are dedicated to just one game that manage to make daily videos with little guides in them all over YouTube. It's more or less just "pick a game mechanic/quest and write a small guide for it."

These people are complaining not about having to write so much, because it really isn't much, but they're complaining that they have to write directly about video games that people play instead of industry drama. They are supposed "game journalists" complaining about having to play and write about video games.
