I didn't buy SSE so I can't comment on the actual quality of the game, but I do think that some of the comments here show a lack of understanding in just what is involved in producing something like a ship simulator.
Apart from the fact that there are no specific issues raised here just a general "it's rubbish" kind of attitude, the main gripe seems to be multi-player.
Most multi player games consist of a fixed fairly complex environment in which small characters with simple physics move around, Shipsim is a relatively simple environment in which complex characters (ships) with highly detailed physics move. So of course there will be issues, do you really think that having a kiddie tantrum on an internet forum is going to help make things better?
