Found this site when search for some more info about ED (google search for "Elite dangerous reviews" and reading through reviews was quite interesting. From what I have read is, that summary is like "It have a great potential but it is so empty and not finished yet ..." "Things looks really cool, but are still the same" ... etc. (and this also from latest reviews). Could be good idea to look there if you are deciding if buy now or later.
