The problem is that the second Trackers Alliance mission,
The Vulture, is only available as a Starfield Creation, and it sells for $7—which is really $10, given that you'll need to purchase 1,000 Starfield
Creation Credits in order to have enough to access it. The Vulture is an official Bethesda product so, leaving aside jokes about
Bethesda jank, it's safe to assume there's a level of production quality that's not always going to be present in fan-made stuff. Even so, there's a widespread feeling that it's a lot of money for a single quest.
