Is size necessarily an advantage? I imagine a nuke or a projectile moving at relativistic speed would be capable of doing serious damage

[/quote]Not a classic nuke but space opera settings can easily get to the level where ships can wipe planets with their firepower.
Besides, those ships are kinda like Death Stars. Are we seriously banning people to re-enact classics like Star Wars in a freeform sci-fi game?
