Please provide more information on this I am super excited to obtain data on non PMF expansion attempt into Sol. Thank you very much for sharing! Part of this experiment would be to test if possibly TDW is different in some way. And the goal from Phase one is to get TDW to Sol and secondarily to check if it will go INTO Sol. So just expanding it there will test if anything happens and then attempting to get it into Sol will yield results either way.
Not much to tell really, it just didn't work. Sol should have been first choice expansion target, instead it went to the system we'd identified as second choice. We went down a similar thought process to yourself:
a) Has anyone else tried it - more than likely but nothing we can confirm
b) Has anyone tried it with a non-PMF - again, more than likely but nothing we can confirm
c) Has anyone tried with current expansion mechanics at the time (possibly not, because no one else on the forum appeared to know how current expansion mechanics worked - not today's mechanics, but those from 3302/3)
d) If Plan A fails, can we force Sol's ruling faction to expand to our chosen system and displace our faction back in to Sol.
We knew point d had been done in one of the capital systems previously (I believe due to just normal BGS behaviour as opposed to intentional player actions) at least once. We'd also achieved that intentionally with our own faction back in Alliance space, so knew how to do it. Unfortunately, we ended up in a player war over Ross 128 before getting the chance to test this.
Point c is, I believe, your only hope for your project. And then you're crossing your fingers and praying. You've basically come up with some wild theory that most likely won't release Raxxla on the player base, and you're pinning your hope on one faction behaving differently to all others to support that theory. You're going to be dissappointed.
