100% agree. Oddly, they’re far better than their marketing images make them look. I have all of them except Nanjing and Guangzhou (both of which I’ll likely add when they’re next discounted). I bought ZSPD a couple of weeks before I actually flew there in reality and was amazed how true-to-life WFSS’ work is — even down to the orange baggage dollies and unique lighting used on elevated sections of landside road. My only minor gripe with them is the night-lighting can look a bit garish and repetitive, but this is most relevant to VHHH and ZSSS. I actually think ZSSS is their least detailed project — which is strange as it’s their latest — but none of their airports are poor. For me, ZSPD is definitely their standout scenery.
MK Studios’ Naha is superb and partners well with Narita and the numerous freeware airports. Best of the freeware bunch are Osaka Itami (https://flightsim.to/file/51064/osaka-intl-airport-japan) and Ishigaki (https://flightsim.to/file/67482/roig-new-ishigaki-airport-japan). Both are payware quality and are probably my two favourite freeware airports for the sim.
Technobrain’s Kansai is apparently good but I hear it’s showing its age a bit now. Don’t think it’s been updated in a long time. They are releasing Haneda quite soon and that does look better.
I also hear positive things about ACO’s Taiwanese airports but, again, they’re old and I’m not sure how frequent updates are. They also feature default Asobo jetways, which really puts me off.
I have Singapore, by Cloudsurf. There’s another version by Imaginesim, which is newer, but it’s more expensive. Both have flaws but the Cloudsurf seems to be the more highly-regarded one, overall.
Siamflight’s Thai airports get decent reviews but they always look a little sterile for my liking. But the level of detail is good and you usually get plenty of surrounding POIs to enhance the approaches. VTBS looks particularly nice but it’s pricey, even in sales.
I’ve often looked at Samscene’s airports but have never bought one. I like their city packs but their airports look sub-par. Still, they’re pretty inexpensive so I suppose it depends how much you want what they’re offering. Xiamen and Sanya look quite nice, admittedly.
I see The Secret Studio’s work has been mentioned. I don’t own any but a friend who does wasn’t particularly impressed with Kuala Lumpur.
Unfortunately, there’s far less choice for Asia than for Europe and North America, so there’s perhaps the need to be less fussy since there are no alternative options for most airports. If you want Kuala Lumpur, for example, you’re stuck with The Secret Studio.
If you fly as far west as Bangladesh, Final Approach Design Studio offers Dhaka and Sylhet — both really nice airports.
There are of course many more Asian airports available but most of them are lacking in quality. Some people don’t mind more rudimentary airports but I like mine as realistic as possible.
