I bought it this weekend after Las talked me into it (not really, didn't realize there was so much to do in beta already) and the mouse/keyboard controls are indeed sucky. Been playing with my PS3 controller which is okay for normal flying, but is horrible in combat. So I ordered a cheap(ish) joystick since I will try out Star Citizen sometime too. And I might replay Freespace 1, its expansion and Freespace 2 again with
Freespace Open (Volition gave away the source code to the engine and it's made to run at high resolutions on modern hardware). You do need the Freespace 2 installer, but it can be bought from GoG for cheap.
Only played a few hours and only in solo mode for now, but the game looks stunning. Tried some of the tutorials, but while they tell you what to do, they don't really tell you how to do it, so I was constantly looking at the controls on how to do some things they tell you to (been a long while since I had to do that

). Still no clue on how I have to do the combat tutorial vs the 3 normal ships and 1 hard ship (supposed to use silent mode, but my ship overheats stupidly quick and then I get shot down)

.
Decided to just jump into the game and did some cargo/courier missions which earned me enough money for a new ship: an Eagle. It looks cool, but hardly has any cargo space which is why I decided to get into a conflict zone with disastrous effects. Luckily I had enough money to afford the insurance and get my Eagle back.
