Yeah, dude, because the gameplay in ZA isn't repetitive.
>fleshed out open world.
Now you're taking the piss. That mix made so the wild areas had to be very tiny boxes and the city to be an empty grey hellhole. That fusion didn't worked out. 
>cafes
Are you serious? You can't even see them from the inside.
>Different sidequests
Have you played PLA? That game wasn't a masterclass at sidequests, but it was so much better than whatever we have going on in ZA. Most sidequests comes down to "Oh, do you know about this movie that you've used 1000+ times? Battle me and I will give the TM". Wow. Riveting stuff. 
>seamlessly
yes that it is the strongest aspect of the game but having a dead city, that feel less alive the Goldenrod in GSC isn't a good tradeoff. 
Also PLA had a more fleshed-out sidequest to catch the weather trio than ZA had to catch XERNEAS AND ZYGARDE.
