Overall X-Blades isn't a horrible game, it is just repetitive. If you can look past that then you might have some fun going through the campaign. It has an rpg-ish system where you collect souls and then you use those souls to purchase and upgrade spells you already have. As such, there are some really expensive spells that you might have to purchase so you might have to spend some time simply leveling up.
There are also various artifacts for you to find around the levels which will help to level up your skills as you progress. Totally360 would definitely recommend that you rent this game before you buy. If you enjoy what you see then by all means pick it up at your favorite video game store. If not, then you have a nice rental.
