Put it another way - "Space is big. Really big."
I don't find the gameplay anywhere near as flawed as others. I'm also not the kind of person to nit-pick their way through all the plot-holes in a film either; I'm happy to suspend disbelief and immerse myself.
Sure, there are some howlers; Eg: Ally yourself to The Federation but rank-grind for Imperial ships because they look nicer? Okaaay.
I've played a lot. There's a great deal of repetitive gameplay; it's what the Frontier/Braben franchise deal in; if you don't like grindy games, you probably won't like E:D.
