I don't think the Persian Gulf map and NTTR are really comparable. If you're wondering why nobody flies on the NTTR, it is because of how limited it is with possible missions. Plus the setting never feels right for any operation that is outside of the training realm. Whereas the Persian Gulf map is ripe for possible missions, both historical and fictional. Its timeframe can span from the 80's to present time. It's the perfect home for the Hornet, Tomcat, F-5, MiG-29, MiG-21, etc... I think it will compete very well with the Caucasus. Especially since many of us love CV operations, to which the Persian Gulf is currently the only realistic option for that.
