I think why this is necessary working with steam platform. There is certainly an interest from Non EU or US wargamers but some of it costs a fortune. -in their native exchange rates-. I've bought War in the Pacific before from Matrix games(6 years ago) but not Warplan game now as it is very expensive. Cheers.
For a comparison I've bought Strategic Command WW1 with a price discount from owning previous games I have paid around 40 TL. Originally it is 61 Turkish Lira for Steam.
