IME they're roughly equal in terms of raw skill and experience required to publish a finished product. Its a bit apples to oranges however, there are some things in developing video games that are much more difficult than what I've experienced in non-game programming. A lot of it depends on the complexity of what you're making - you can make games that require almost no programming whatsoever, but some games require a great deal of technical skill to program. For instance, running a large-scale multiplayer game isn't so different from managing a large-scale web business.
