I'm looking around for some figures to base this on.
I could use per capita GDP [1] but I'm not sure GDP is all that good a measure of how much spare cash an average person has so I'd be interested in any alternatives.
I'd be grateful for any ideas.

EDIT: the text "... but I'm not sure GDP ..." originally read "... but I'm sure GDP ...", this was a typo.
Since then, Robin switched to simple tiered pricing based on pure product levels. (Plus maybe Patreon?)
I think this might be the better approach:
1. Offer your base product for a low price everyone in the world can afford (even free).
2. Then offer people who can/wish to pay more the option to pay more, possibly with incentives/upgrades.
Another option is to offer your product at a high price, then occasionally offer discounts so people who can't afford the high price also get a chance to buy at a price point they can afford.
I see two major issues with setting prices based on a country's wealth:
1. It can be "gamed." I used a VPN to check the prices of Road to React in other countries.
2. There are rich people in poor countries, and poor people in rich countries. So you risk excluding poor people in Luxembourg (like students, for example).
Say you take the poorest country. Make it free there. So make the price something like P=aG-b, where P is the price, G is the country's per-capita GDP, and b is chosen so that P=0 in the poorest country. Choose a such that it gives you a price you think is reasonable in the richest country, and there you go.
