In short, I agree 100% with Leigh's post, and I say this not as someone who's never thought about it from this angle before and is kneejerk-reacting to say "what a great new idea!" but rather as someone who has held essentially this position for years. (Not to imply that others here are necessarily kneejerk-reacting; it's just that agreeing completely with a post has the potential to come across that way, and I want to be clear that this is a really deep agreement on my part.)

But I also want to mention that this isn't necessarily an unhappy topic. Just as games that glorify violence can desensitize you, games that brush upon it and leave you horrified at what you've done can sensitize you. It cuts both ways, just as any form of exploration can do.
