If I post about a tree, my opponent is more than welcome to blow that tree up. I post about a car in the background, you can interact with a car. We are supposed to interact with the setting, not just each other. Why this inane bubble exists around ships and ships alone is beyond me, but frankly it's both moronic and immersion-breaking. Why not just not have ships?
On my next character, I will give him an ordinary earring, but no one is allowed to post about it or even acknowledge it IC.
After, this is about character vs character, not character vs. earring.
And then there is the irrational vehicle hate. What is the functional difference in terms of the story between a sword and a tank? One is a tool a character uses to kill, and the other is...a tool a character uses to kill. So long as the character using the tank is balanced, what is the problem?
