Not really cities though, I know you said suburbs but still they aren't too big at all.
I lived in the UAE for 5 years, I lived in a few "cities" like in Dubai you have places like Sports City, Production City, Media City, International City and so on.
They're tiny, you can drive across the majority of them within 2-3 minutes. I lived in Sports City and you can drive out of it within a few minutes, and then onto the E311 to go to elsewhere within Dubai.
The majority are "themed" but Sports City has a cricket stadium and that's about it. There's "Science Park" as an area which no science goes on there really.
I mean I can't imagine a Pep City at all, they're mostly named after things they want in the city like Internet City... has a few technology companies there like Microsoft, Oracle.
They feel a lot more like tiny neighbourhoods to cluster a few things together.
