as of right now i think anyone who wants to play MP should definitely keep .81 or hold off on 1.0 for the time being, as after trying with 3 different people we have had no success in running the game on MP, everytime it gives a not the same game data screen when someone hosts. just a heads up i'm sure it'll get fixed eventually but for any of you who have become addicted to MP(like me) make sure you keep .81 til it does get fixed
