I played my friends copy of it and i played elite and dangerous problem i ran into with the game is just way to many key bindings every single key pretty much on keyboard does multiple things. so personally think the control scheme needs be simplified a little.
my rise of flight simulator and even the mechwarrior simulator online doesn't have that many keybindings.
there's some good tools out there that really help fix the poor UI problem, but not so much for the learning curve. I spent my first 5 hours I think just watching tutorial videos on Dwarf Fortress...jumped in and was still confuse x.x
