The issue with this is if you don't know what a fighting game is, explaining the genre would take up a lot of space in an article targeted at gamers that know the genre. Sure they could have opened up with "A fighting game, like Street Fighter or Mortal Kombat", but you might not know what those are either. This is like an article about React getting posted and complaining that you don't know what a UI or Javascript is. At some point Google is probably better at filling gaps in assumed information than the article itself.
