Based on first hand experience, no it's not that hard to get out of games industry, not for a sw dev anyway. It's true that (for example) intimate knowledge of real-time 3d rendering is a rather niche skill, but OTOH knowing how to write fast code has much wider applicability, and most game developers will tend to be much better at that then your average sw dev. If anything, it's harder to get into the games industry than to get out because there is relatively more competition for gamedev jobs than for other sw dev jobs. So I would argue that if you can get in, you can get out, and when getting out you have the added advantage of being more experienced than when you got in.
