An eight year run does not make a failed game.I bet if TOR wasn't being made SWG would still be around. Call a failure all you want. The fact it lasted eight years says otherwise. Failed MMOs don't last half that long.
The only reason it lasted 8 years was because it was licensed to run. If it was LA's or SOE's 100% owned development team on it they most likely would have pulled the plug.
And yes, SWG failed. They projected nearly 1 million players at launch and barely got 1/3 of that. So I'd say they set their own expectations on how good their game was.
