I have a few paid for several addons, the planes are great (and I would happily pay for the Hype helicopter, with steam gauges though, the digital displays don’t work for me in VR but that’s another discussion), the airports, less so since many have bugs that will probably never be fixed. I understand the value of a paid add-on but mesh updates are not something I would be willing the pay for and as @SteepFarez points out, detailed data exists for free, so why haven’t Asobo used it?
