So, I'm going to buy Darksiders II on my Wii U... but

[Paatar]

Should I get Darksiders on the 360 first? Do the stories overlap that much? I know that the story with Darksiders II has to deal with War, but is it that much of a deal? 

I watched a lets play of Darksiders not too long ago but it didn't interest me, which is odd because Darksiders II does. I think it's the improved combat (at least it looks improved on II)
