Yes, if it comes up, I don't mind saying I'm a gamer. It probably helped get me a job, because I could say I helped run a small press publishing company (ooh, impressive, thinks my interviewer; what'd you publish?), putting out rulebooks and supplements for D&D (huh, that's kinda weird, thinks my interviewer; what do you mean?). And then I explain, since I've gotten good at explaining D&D to non-players, especially the business aspect, since people seem to respect a company that sells games more than they respect a person who plays the games.
But yes, I never have a problem with saying that I game, unless by the person's previous comments I suspect it will just cause an argument. That doesn't happen much anymore, though.
My old Creative Writing advisor, though, still thinks my fiction is too D&D-ish. I try to explain to him, "At least it's like a D&D game, and not a D&D novel."
