Most games will be running on an engine the studio bought, if not, it's usually one maintained by an in house team. Which is, I suspect, the reason why some gamedevs are hesistant. For Linux they not only need the QA track and development resources but might have to redevelop some engine customizations for Linux or the engine might not even support Linux at all. They're two steps removed from the people who would be responsible for making the engine work on Linux at all.
