It’s certainly an interesting product.
Judging from the World Updates up to now, and the improvements on the simulator’s mesh from Asobo, I don’t think I’ll be buying 10m resolution meshes anytime soon - seems like something that will be included sooner or later.
Furthermore, there’s plenty of data (elevation and some impressive 50cm/pixel and 30cm/pixel aerial photography) from NZ, all licensed under Creative Commons 4.0 and freely available for personal and commercial purposes - including LiDAR (Elevation data | Toitū Te Whenua Land Information New Zealand).
