Worth Playing?

I'm not the biggest gamer by any stretch - I own a Wii and a 360 but apart from Grand Theft Auto IV and the Lego Star Wars, Indiana Jones and Batman games I don't really bother with anything else . . . and yes, I know GTA IV and Lego games may indicate some form of split personality but hey, I like them.

Anyway, to get back to the subject of this post, I've just watched the following trailer for the Batman: Arkham Asylum game and I'm intrigued.

I have to wonder, though, whether it's a beat 'em up, face a boss, defeat him then progress to the next level because if it is, it's a little less intriguing.

Any thoughts from the gamers out there?
