Honest
Its not the boring hack and slash over and over, it really got me when it started giving me puzzles which sometimes really got me stuck for some time, i appreciate they did that, we need to exercise our mind too its not all about souls and enchanted swords :P.
The storyline was good enough to keep you wondering what will happen next with many unexcpected events which gave a better "flavour" to the whole gaming experience.
They could make it a little better but i look forward for their next Darksiders 2 or something :).
Nice sound effects depend on the situation you where, graphic were very good very detailed with a dark/violent theme.
You should play it, its fun.
