So, with the galaxy split happening in Update 14, it would be great if the Legacy-mode of Horizons was used to test Open-only Powerplay. This in my observation would begin fixing relations with many of the organized powerplay groups.
It's the perfect solution to a controversial update, a split galaxy that can only be affected in Open play would at least give some players what they want.
3.8 is going Legacy - as in maintenance mode - no updates, no dev.
It simply gets frozen in the current state, as is at the moment of the split
It's not going to be an offline mode, nor a open only mode.
Just the good old 3.8, with bgs, with pp, but no narrative, no cg, no galnet.
I guess the expectations would be that it will slowly get devoid of players and die.
However, that remain to be seen.
I think FDev might be doing some experiments here too...
