--- Comment #3 from Anton Romanov theli.ua@gmail.com --- I've just sent a patch to wine-patches that makes mtgo fully playable(as far as I could test by playing trial event) in wine master (after installing dotnet452). Patch just fixes connect to server problem, otherwise it just seem to work as is.
