Whether the term "vaporware" applies to SC is kind of subjective IMO. The server meshing feature has been advertised for a long time and it still hasn't been shipped. Though they did add object persistence a few patches ago which really changed the game for salvaging.

I bought the game based on what I see people doing in it already, and it was fun enough for me. That definitely won't be the case for everyone and I recognize that. So to me it's not vaporware and there are lots of other people still enjoying the game today.
