This is a great sequel to Path of Radiance, but it's not for everyone.
The gameplay is very good, especially for the fight sequences, and the short movies are decently animated. The voice acting was pretty bad, however.
As you get to know the characters, you wont like everyone, but you will manage to find at least one person that you will become a fan of. The change in Sothe's character is pretty unrealistic. No one changes like that just three years.
I think that to truly enjoy this plotline, you have to play Path of Radiance first. Otherwise, you may not understand some major parts in the storyline.
Overall, this game is great, but it's not for everybody. There are some really tough levels in this game, which means you have to think hard to get through them.
So, here's my advice to you:
If you are brilliant with strategy, and you want a challenge, this game is for you. If not, then you'd be better off without this game.
