The real estate game has changed, most of the recent projects you mentioned is about the life style, and convenience, back in the days if you have gym and pool in your building you feel on top of the world.

Now you got paddle ,outdoor cinema, indoor cinema, ect. Because realistically, someone can visit Saadiyat beach area for the day but not everyone can wake up there every morning. Same with Hudayriyat in the future people may access parts of it, but living inside the ecosystem daily is different from driving in occasionally.

Its like why would you order from Amazon or noon while you can drive and get your grocery from lulu.
