I see tons of comments from people claiming refunds because the game simply is too 'simple' in its design.
I think some people just don't do their research before buying to be honest. Many bought into ED off the fond memories of games like Privateer, Wing Commander, Freespace and X-Wing types of games and expected to be led by the nose through an epic story-driven game with them as the central hero. Even some of those that knew it is a sandbox still expected a fully scripted story mode and were disappointed when they found there wasn't one.
The original games had no intention of being that type of game which set it apart at the time and ED follows the same path. FD had no intention of giving the average gamer what they wanted as what we would have got is another Call of Warfare Medal of Duty clone. FD wanted to continue the Elite franchise for themselves with modern graphics and if some of the general public liked it then great. Don't think for a second that FD are pandering to the general masses though as they know that ED-style gameplay isn't for all. ED is the opposite side of the Star Citizen coin.
