One thing you can say about Darksiders is that it isn't original. It takes a lot of elements from highly revered games. But one thing you can't say is that Darksiders is uninspired. The people at Vigil have obviously worked really hard to make sure that the quality of all of those gameplay elements stand up to the games they came from.
This is no cash-in. What at first seems like a God of War clone turns into a grown up version of Zelda - a bloody adventure with dark themes and settings, and it actually works. The puzzles are clever, the combat is visceral, there are a good amount of items and upgrades to be had and the world is convincing. Darksiders might not be very innovative, but it is without a doubt a 3rd person jack of all trades that shouldn't be passed up.
