The question doesn't need elaboration in and of itself, but most probably know what New Eden is. Perhaps there are multiple, but what I'm thinking of is the setting of CCP's mmo Eve Online. Four major human civilizations with space-faring, cloning, and mental copying technology. FTL technology for intrastellar travel, jump gates for interstellar travel. Rail, laser, torpedo, and projectile weapons, shields and metal reconstructing defense technologies.
Besides my love of RM, I was wondering about SM's suitability for New Eden because different weapon types(sometimes down to the ammo) have different strengths versus the different defenses and each empire's technology has a small additional resistance and weakness. I thought SM might have the same attention as RM's treatment of piercing/slashing/crushing damage against leather/chain/plate.
