Come on, when was the last time you played a 4 for 70 hours. A 6 or 7 sure, but you played and talked about the game non-stop for 3 weeks. Talking about how you didn't want to work, just wanted to play all day. A 4 does not do that to you.

There have been plenty of games over the years where I got hooked on one aspect that was fun or compelling, only to tire of it much later and realize the overall game was actually mediocre and just happened to scratch the right itch for a while.

Open world RPGs tend to make up a lot of that list since they have repeated content that draws you in the first time you encounter it, but wears out its welcome by the hundredth. It sounds like Starfield had this problem, combined with a terrible fast travel system that gutted exploration and threw the samey content into the spotlight. Once the new game shine wore off a lot of players were like "is this it?"

(I'll note that I haven't played the game yet, this is just the gist of the complaints I've read)
