Personally I think they should offer this as part of the
Station Players Premium Service as well. I don't see why a small charge can't be offered for the same thing, instead of purchasing a plan to play other games one doesn't intend on playing??
There are those of us who want to stick with the one game and are enjoying it quite extensively, and don't plan on playing the others anytime in distant future. But still would like the benefit of additional characters...
