Well, prefering one game to another is a matter of personal taste. But putting taste aside, it's clear that good modern games are rich in content, while some older games can be beaten in one afternoon.
It's funny you naming Returnal, I got the platinum trophy this weekend. Took me more than a month to fully finish it, and it's a great game, arcadey, fast-paced and challenging. I believe it will get some cult following and it will be viewed as a underrated gem in the future.
Gravity Rush is fun, but the first is very short and have too little content. I can see people feeling disapointed by buying it at $40. Gravity Rush 2 however has a lot more content and is more deserving of having the $60 price tag at release (i think that was the price).
