I'll just copy what I posted in another thread.
My review of the game will stay negative until the issues are solved. There is no transparency on the status of the MP fix and the same crash pattern for over 2 years is inexcusable for a full release. I encourage anyone who takes MP seriously to have their voice heard through a negative review, so as to prevent the next player to spend money on an unfinished, but advertised feature they may otherwise enjoy.
