While I can nod my head to a lot of what you are saying Walt, the problem with making it by value pushes people into the big ships.
The game already pushes players into big ships. Big ships are already carrying more "transactions" than small ships.
My Cobra could carry 10 tons of four different commodities. My Type-10 could carry 10 tons of forty different commodities...
Even the mission system pushes players out of small ships.
"Carry 128 tons of biowaste to Sol"
"85 senators seeking transport to Sol"
I believe that the system being value based would make more sense; it would be more intuitive. Until I read this today, I had no idea that me trading 400 tons of Advanced Medicine to a system in Outbreak was basically completely ineffective. The system working this way is totally counter-intuitive; in the course of playing the game in a normal way I would have
never assumed that. The system being transaction-based means to be as effective as possible you must play abnormally.
Dear God Why???
I don’t know for sure, but before we call anyone stupid for a horrible implementation, my guess is that the purpose was to allow anyone, be they in a sidewinder or an anaconda, to have an effect on the game and “blaze their own trail”. Problem is, as we discover the thresholds and frontier patches them higher and higher, the threshold will become out of range of the sidewinder, but still provide an exploitative spamable transaction giving the worst of both worlds.
Only Frontier can really say why.
I think the reason FDev did it this way is because they never expected the BGS to be something that players would focus on and actively try to manipulate. It was just something that should provide a changing game experience that players wouldn't really pay attention to. But players being players, and people being people, some did take interest and it's completely understandable why they would. Then FDev introduces PowerPlay and tacks it onto this system that was never meant to be focused upon, which gets even more players into manipulating it and really brought the flaws and shortcomings to light.
