What would you say changing your links from using underscores to hyphens would be? Is that gaming the system, or making a better website? I mean, from a programming perspective, it doesn't sound like it makes much difference, but from an SEO perspective, it makes a huge difference. Google recognizes words when they're hyphenated, but not necessarily when they're underscored. Your rankings will probably improve just by doing that. Its simple things like that that programmers should be aware of, and its not really gaming the system, its programming to match what Google recognizes.
