I honestly don't care all that much about not being able to walk around my ships' interiors, and I don't really care about any FPS aspects being added in (If I want FPS, I'll play CoD or something else like it).
I just want some new gameplay (new mission types that aren't just a variation of what we have now), or expanded/improved galmap functions, Community Goals, the return of GalNet, etc. Spacelegs on planetary surfaces (even if we can't do it on Earth-likes, which of course is what everyone REALLY wants) is fine, but if that's all it is then... well, I'll be disappointed.
