That's one game, not 'most'. Lots of games don't even have characters at all, let alone character development. It's bizarre for someone to say "most games don't have character development" and someone else says "here is one game that does". This person said "the best games have in depth character development" when it's very rare even in the biggest and most popular games.

I read that as a simple recommendation, not any kind of attempt to disprove the thesis. I see no language indicating otherwise.
