Considering your avatar, I wouldn't expect much. Every narrative twirl they've thrown my way has been caught and tossed aside like a little league infielder. The Grand Twist I consider will probably be either one of two things considering the setup, and neither are very complementary to the narrative if they follow through with it in the end. I want to believe, but it seems they followed the I<3SS2 narrative a little hard thus far. Hope I'm wrong, but it's either going that way or explicitly not that way for the sake of people who played BS1 and SS2.
Be in this one for the systems.
Ok, thanks for the heads up!
