Ask HN: Any game devs who switched from business apps dev?

Any game devs here who started off building standard business apps? If so, would you say you became a better dev or more passionate about the craft i.e. software dev? Things learned or unlearned. Looking to know of the contrast between these two dev fields that are in my opinion a world apart. What were your challenges during this switch and your learnings? Would you ever want to go back to building business apps or is this (game dev) a career of a lifetime?
