I can not comment on SM as I never played. I respect Ritchie and Sheats and their notable achievements in pinball.
Not sure about Avengers having many many bugs? Playing 1.4 seems to be fine to me.
Well Hulk did say to me the other day that I was weak and no match for him at the end of the game. I managed to get Grand Champion with 248 million. If that is a bug in the code, I can live with that.

Very interested in you views on avengers cause you actually have one so keep them coming.
