Although I kind of agree, this is the sort of thing that looks very strange to outsiders. "I've watched every episode of STAR TREK seventeen times and I tell you it's totally unwatchable!"
I can kind of understand it with ED. I've completely burned out on it, but I wouldn't hesitate to recommend it to any space junkie. Having said that, I get where people are coming from. It takes forever to do anything in ED. It's not the kind of game where you can experience any amount of the content (content meaning ships/modules) in a week unless you exploit the crap out of it. The repetitive nature of the gameplay doesn't sink in for a while either. Once the novelty of flying the spaceship(s) wears off, the grindy gameplay hits you and you suddenly wake up to what the core of the game is. For some people, the novelty is long lived, for others not so much. There was also a lot of faith put into the game, particularly by backers and beta backers (like myself) for what the game would become. Over the last 3 years it's become evident that the direction the game design is taking isn't to everyone's tastes and this will also lead to negative reviews as people feel they've been misled. It's taken a long time for us to get what we've got so far and it's not that much more than we had 3 years ago.
