Late to the party as usual. Everyone who was onboard since early beta and before probably has their own pet portions of the DDF that they were hoping to see put in. For me it is exploration and that's one genie that cannot be crammed back in the bottle. I'm the first discoverer of several thousand objects by now, but so what? Until you go there, too, you'd never know it, and until I go there again, I'll never remember I was there before. I spent several weeks trying to help the 2,000 people in the Tyerisu system kick out some evil criminals from the one platform by hauling in tons of supplies, killing hundreds and hundreds of criminal faction ships, and doing missions for them, but you'd never know it. The galaxy is static and so homogenous that even Power Play can only add a curiously disconnected layer on top of it. The gee whiz payoff of grinding incessantly for a faction leader is the ability to grind a larger volume at once.
At the risk of sounding like I want to be a special snowflake in the storm...well, guilty as charged to a small degree. The game badly, direly needs an NPC presence and feedback, because right now NPCs are just hordes of goofy named pirates for me. I have no connection to anything, and I like to think my imagination stretches as well as the next person's.
