Interesting; I think the questions could have split the open/ solo/ pg into two, due to solo having no player interaction, and pg allowing it, eg:
1) Do you play in open for > 50% of the time (y/n)
2) If n, which mode do you prefer for > 50% of the time (solo/pg)
Solo and PG are essentially 'not open', split the vote, but aren't interchangeable. Leading to the usual three-way that always causes people to argue semantics. It means the majority of those surveyed prefer some degree of multiplayer aspect, though. Note that multiplayer and pvp do not share 1:1 relationship. And, again, PG and Solo aren't interchangeable, regardless of what people want to believe, so that always needs to be clearly split out.
Frankly, with the amount of screaming about death in open, or in general, I find it hilarious that C&P is like sixth place; more ships, planets we can breathe on, legs and places to use legs seem to rate highest. So much for crime being a hot-button issue on the internets (outside of hotel california).
But stats, are stats, and they can be made to say anything. Remember, it was a sub-section of ED, and a minority of the overall player base that voted for delayed ship transport in a survey; so don't be so fast to claim the numbers are made up and the points don't matter, if you were also claiming Frontier's little ship-transport survey was somehow statistically relevant enough to force a change.
~12601 people responded. Out of how many of the player base? At most, the numbers are interesting and provide a little bit of a trend and a bit of an insight into the hive mind. Thanks for posting, OP.
