These are not rules. They are SUGGESTIONS. Suggestions for personal rules…or better yet…personal guidelines. EVE itself does not have in-game rules. It has mechanics.
I never was a fan of guideline number one. You can afford to lose ANYTHING. Its a game. You started from practically zero once, you can do that again. The question is if you can emotionally handle a certain loss, particularly in any possible purely in-game situation. If you can’t, well maybe don’t fly that ship or fly with that mod, rig or implant…don’t even make or buy it!
I will also add a ninth guideline. 9: You CANNOT die. Even if you think you died, you didn’t. You will be resurrected. You are immortal. So stop worrying about your flesh cage getting blown up except to try and not give loser thugs the satisfaction.
