FSX. The japanese designer is extending his Real Addon Series with a new episode : Approach Adventures North. This product provides real ATC dialogues in a selection of 21 Japan airports located in the north of the country (Sapporo, Akita, New Chitose, Fukushima etc.). It also includes all the charts and a special observer mode to learn from the cockpit before your real approach.
So of course, none of the previous Aerosim airports sceneries are included and this new product doesn't provide any new scenery. Another limitation comes from the aircrafts used ; the awful basic B-747, the B-737 and the A-321 from Microsoft. The price is awfully high for this kind of product (39,90 US dollars) although i am certainly not doubting of the time of development needed...

While Aerosim is working on Osaka Itami (we hope so), the designer will also launch Approach Adventures East, West and South.
