Hum... Writing a game engine is a high-difficulty task that should be available to any reasonably good software developer with a few months to study for it. Making it in assembly is a sure way to take 10 times the time of another low level language like C, but shouldn't be an impossibility either.

Configuring a web server is a low-difficulty task that should be available for any good software developer with 3 days to study for it. It's absurd for a developer to need to configure a web server, but insist on paying a large rent and cede control to some 3rd party instead of just doing it.
