I will say I have to modify my comment about flyers. I like 'em deadly but vulnerable, or ineffective but safe. I played a game where there was boarding by folks standing on the ground. Never got high enough to pass by.
I know Tharks are tall, but not THAT tall. Cloudships are not hovercraft.
But I accept there's no Norton bombsight, that navigation shouldn't be pin-point. Flyers may be high ground, but if you can shoot, you should be able to be shot. Just, I think a player with a flyer should be able to make the choice.
Simplistic, I know.
