FFE's bulletin board system is so much more realistic, and thus immersive and compelling to play, than ED's "duh, missions!" board... and now its "passenger lounge". There's none of the forced hammy neuroticisms of passenger 'likes and dislikes', or "sourcing and returning x for the glory of y" - i browse the available missions in ED and am totally put off by every single one of them; they're all weirdly over-particular, over-familiar and uncomfortably 'personal' what with the relationship management tripe and "Greetings Commander x, blah blah rhubarb rhubarb" inanities; having spent a lifetime working in the transport sector, FE2/FFE are convincingly realistic - it's just an impersonal list of random jobs - some passengers or cargo need to get from a to b, with a deadline of t, and will pay x: precisely how this work is handled in real life.
Plus FE2/FFE have space ships, moving through space, whereas ED has submarines crawling through overly-thick custard. There's no restrictions on yawing, and no space speed limits - 'faster' ships simply accelerate or decelerate faster, and with Andy J's FFED3D you can map a HOTAS precisely the same way as in ED, and so fly the same way, just without these game-destroying constraints on freedom of movement. Rolling, pitching and yawing, at equal rates. Launch from ground to orbit in one fell swoop, seamlessly accelerating up to whatever speed or altitude you like, just like a real spaceship launch but without its fuel restrictions.
Proper orbital mechanics - none of this limited hard-coded rubbish you get in ED - orbits can be as eliptical as you like, so you can perform proper white-knuckle high dives, the ultimate extreme sport. No clunky artificial "orbital cruise" and "glide mode" interrupting the fun. Slamming into a thick atmosphere at Mach 50, skimming mountain tops as your hull starts to boil away. Leading a pack of attacking pirates down into a giant crater to pick them off or force them to crash.
That's Elite, to me, and FFED3D nails it, while ED misses the mark by a country mile.
