johnki: I didn't bother with the second one because, for someone who's played Zelda, the first one was nothing inherently special. It was pretty much Zelda with a new setting. I do get where that would be appealing to people that don't generally, or never, own Nintendo consoles, though. So it was a good game, but nothing that made me want to run out and pick up the sequel.
My first thoughts when playing Darksiders was how remarkably similar it was to God of War. Admittedly, God of War was the most recent action game I had played before Darksiders, but I liked God of War, so it was all cool. I hadn't considered it being like Zelda, but now that I think about it, it does share a lot of things in common with that as well. Of course, I liked Zelda also, so I'm fine with that, although I think Zelda had better dungeon design.
The thing is that I played both Zelda and God of War on console, but Darksiders on PC, and the port to PC is a little bit of a pain, but it's manageable.
