You can add my girlfriend to the list of players hooked by MarvelScape. I figured that Marvel would be the easiest way to get her to play since she knew the figures and it was. It also didn't help [her NOT become addicted] by crushing me with the Heroes (minus Hulk) in the Basic game.
Just this past Sunday we played our first Master Classic game and she beat my WoA, Greenscales, and Charos with her Marrden Hounds (she didn't even have to use her Warriors, and SBN only slaughtered Charos). She trash talked me the whole time.
