Awesome game that should not be only kill and move along.
Now let's see the thing where this game fails. There's a lack of puzzles, so basically you just have to be able to kill everything that crosses your path and move along to the next town. So in the end this game becomes just a kill-kill adventure, where you won't need to work your mind in puzzles, just real for some tactics when you see a mob blocking the way.
Anyways it is still an awesome game and at least you take almost a year to beat it, so you shouldn't have any doubts as to spend your money.
