I'm assuming that if it were worked out and for story purposes, a vessel of beyond 10km would be accepted but the decision to put a limit on size like that is acceptable to me. Also, ftl speed limit regardless of type is also acceptable. Not everyone here is that well versed in science and I for one am not going to go to wiki to look up different properties yall throw out when I could be writing a story. All in all, happy to see a new RP starting up!
