The Falconeer (good Indie game, btw). I definitely would not be able to fly on the back of large birds dogfighting with others doing the same. I would not fare well as a sailor either (another big sector of the game world’s economy, at least when considering what NPCs are often doing). So I would be stuck on one of the countless islands not really making a living. Indeed there is the Mancer Order, who have a lot of workplaces in archives, libraries etc. (besides more manual labour) but unless they make good enough spectacles (their tech is still not ours) I would not be of much use to them either.
