I've added a prepay option to my Store, mainly to keep some sort of income stream prior to the release hopefully later this year.
This is aimed mainly as the real Godzone supporters, who mainly reside here on NZFF. Please ask if you have any questions!You can pre-pay here.
Note that the initial release this year will be for Prepar3d v3 and v4 only, the FSX version will follow next year.
The benefits/conditions of prepay are listed on the product page, but basically it'll cost you $30, which is a saving on the expected price of $40. (Yes, there will be a price increase over the usual Real NZ price of $35, the actual amount is not yet settled by will probably be $40.)
The only other benefit is that you'll receive a multi-sim license, which will cover all the simulator versions of Christchurch which I may release. A 'standard' license will cover the MSFS versions only initially, with an additional (discounted for existing owners) price for the Aerofly FS2 and X-plane versions.
