Wait so I've grasped the wrong concept then. So, it'll be an like a game update, you'll pay $40 for characters besides the free 4? Hm.. Makes a lot more sense. And it's an interesting spin. Well then.. Not bad.
Yeah think of it as the trial version of VF5: FS characters were free to play not all. Story mode is separate too. So that tells me your probably only gonna be able to play these 4 in offline modes. Story mode excluded clearly. Also price is not announced mind you BUT all dlc that comes separate it almost always has a bundle feature.
I love the way the story is not included in the free version, as if they think the story will somehow incentive someone to buy it when they otherwise wouldn't.
