What's the difference between Sub Command and DW?

[Molon Labe]

In a sense, it is an evolution from Sub Command, in that the interface is the same. It's a new physics and acoustics model, though.

I don't think it's fair to say DW is just SC with more toys to play with. The addition of surface and air platforms to drive or fight against makes gameplay in DW fundamentally different from SC. It really is a whole new world.
