Thanks for all the comments - what I have concluded from my very brief experience in open is that Elite is two completely different games.
1. In Mobius / solo. it is a game with:
rules: NPC's will try to steal your cargo, but they won't just open fire for no reason or if you have nothing to steal.
etiquette: NPC's will hail you and warn you before they try to steal your cargo. You can take the decision to fight back, give in, flee.
sportsmanship: NPC's are generally ranked to your combat skill. (similar to a Golf handicap where you could play and have a fun game, even against Tiger Woods)
referee: In non anarchy systems, the system security forces may eventually come and help.
calculated risk: e.g. Since I generally can only play relatively short sessions, I am always getting attacked while mining. I recently tried to fight back in my mining ship with lots of painite onboard, but it turned out it was not just the normal 1-2 ships, it was a wing of 5 that attacked and killed me. That was an expensive learning experience too.
2. In open, it is not really a game. It is a free-for-all with:
no rules:
no etiquette:
no sportsmanship:
no referee:
unknowable risk:
I was in Shana Bei, a "High Security" system for the CG - but in the <5s it took for my 6C shields and 3 x shield boosters to vanish, I briefly saw a message that system security was on the way. Thanks a lot Fdev
I am not complaining, and I wouldn't report the CMDR for cheating - it was quite probably a legit "kill" and the CMDR can proudly hang up another "harmless Type-9" trophy onto his wall. He role-played psychopathic serial killer to perfection.
I was merely disappointed, since I have seen various forum posts and You-tubers saying what fun they have had in Open, so I wanted to try it too. I knew there was a certain amount of risk going into open and I obviously underestimated it. If I had known about, and had time to read, these sort of thread's beforehand then I might have been better prepared !
Kudos on your for giving it a shot. There's a lot more to it than just CGs, as I'm sure you're learning. Head out to Maia. Find some of the cool squadrons around here and join up with them (I think AEDC and GARD just had a nice little war over Helios recently).
Heck, if you're up for a road trip c'mon out to Colonia. Good times galore in Carcosa.
