I've been making games for most of my life and I've been working full time with game development for a good while* and I disagree about skills not being transferable between engines. I feel once you move past a beginner stage you can focus on the similarities and quite quickly learn and look past their idiosyncrasies. I feel it's very similar to learning new languages. Once you understand the common principles and low level details you can very quickly learn and become quite efficient with a new one. * 7 years in the game industry proper, 4 years in surgical simulation
