We'll, the things I'd like to enjoy are broken, for me, in one way or another.
Planet Exploration? Planet tech is broken, for me.
Galactic Exploration? The UI is, decidedly, less than ideal and route planning is broken / inefficient.
FPS in a CZ? The frame rate is, basically, unplayable.
Those just happen to be the activities ED:O was built for and marketed on, no? It was a long weekend here in the States and I played about an hour of ED:O for the duration of it.
I've done lots of planet exploration and even on my 960 it looks great. Issues with some textures, yes. Poor fps, yes. But broken? (as per the actual definition of it not working at all?) Absolutely not.
