I like it. It's an easy game to jump into and play for a little bit without having to commit a large chunk of time to it.
That said, content-wise it is pretty tiny; it's all about replayability over having a lot of content at the start... that's a little disappointing, but I still enjoy playing it.
It's like when I mention "Sins of a Solar Empire" or... "System Shock". People look at you with a raised eyebrow like you're speaking a different language.
It's a fun game, but the only problem is the lack of the campaign. If you want to know each character's story, go here and click on one of the Demigods. They'll display their stories before the game. Once you beat a tournament though, you find out what happens to your chosen Demigod. It's not much, but it's better then nothing. Still, very fun and can last awhile since you can chose to combine different skills. I give it a 7/10.
