I started playing SE just a few weeks ago and I love it. It's really awesome!
I first learned about SE in the Falcon BMS forum. Since I also play Pioneer (an Elite II like space adventure with newtonian flight model), I was interested immediately and checked out the 0.98 version. And when I saw the orbital HUD mode, I thought: cool, that's one thing that I always missed in Pioneer.
Now I have 0.99 and already made my to first custom ships: Apollo CM and an Agena target vehicle, although the models are only *very* basic so far; I primarily did them to try out "visually-aided head-on" docking: it works really good, much easier for me than docking e.g. a Skylone to an X-Wing.
And of course I have also been *inside* some black holes and then looked back at the universe outside
To be honest, the first trip inside was an accident
