Could say DEFINITIVELY without any question whether that statement mean
a) More people play in Open than all other modes COMBINED
b) More people play in open than play in any of the other modes
c) More people play Powerplay in Open
As it seems to me that the statement could equally mean any of those three...
Interpreting a statement is not worthwhile,
it could have a bazillion other meanings too,
like Sandro wishing for the game and story happening in open,
to have interesting and dynamic interactions to base articles and news upon.
Stuff happening in a chaotic mode has been media relevant, just remember the Salami incident.
I won't exclude the cool stuff that solo/pg initiatives created like Obsidian Orbital in the Pleiades,
the colonia settlement and the charity exploration for a cancer patient
(at least those are what i think were solo/pg initiatives).
After all what moves the galaxy is those news that players generate.
But it seems to me that the key stories are lived and felt in open.
That of course is personal opinion.
And even if it didn't, as has been said earlier EVEN IF 51%+ of players use Open over singel-player and co-op player modes is that REALLY any justification to simply and arbitrarily begin deleting major game components from them, for no reason?
That is how democracy works, majority vote and done, doesn't matter if only 1% more than the rest is the deciding factor,
unless clearly outlined before a decision that you need 66%.
I do not think the crusading against this statement is worth the time invested,
unless people want to go for hilarity or salt.
Final words:
I play all three modes, but i only use solo/pg for board flipping,
as the missions generated are not sufficient in number and diversity.
My game happens in open, that is combat, hauling, piracy and exploration,
i had some very enjoyable encounters.
I do not understand why people want to impact and influence a community (open)
via powerplay and bgs, they are not part of and exclude themselves from.
No guts no galaxy.
