No Man's Sky may not be the game you were expecting. It's possibly not the game I was expecting, although I didn't allow myself to be swept up in the hype too much. It is a chilled out survival game set in a proceduraly generated universe where every planet is potentially different, but really after a while a lot of them start to look quite similar! That said, it is a lot of fun, what story there is, is well written and surprising and the game can at times be incredibly beautiful. Performance isn't great at the moment, although I seem to be having a much better time than many - expect patches to improve things fairly quickly I should think.
