It's not something to be feared. It's certainly not something to be ashamed of. Now, we live in a sophisticated age, or at least we like to think we do. I think much damage has been done in the world through the belief that human affairs are simple and only require simple solutions to solve them. RPGs are an opportunity to leave the everyday world behind and explore another place and time.
Space opera is as good a way to do that as any other.
Having said that, I'd like to show you how space opera can become more than just a sub-genre of SF but a style of game play. Think big . I mean, really big. Emphasize the immensity of space, the thrill of star travel, the beauty of the Imperial throne world. Whatever you do, don't skimp when it comes to special effects.
