Alpha Protocol

[greed]

I've been thinking of getting this some time after exams but I'm not sure. It's Obsidian so I'm sure the writings great, but the gameplay worries me. Is combat any fun? Is it a chore? Is it Mass Effect lite? Or more like a traditional shooter? Or is it more RPGish than ME?

On the story, has it got good humour or is it unrelentingly serious? Any really good characters?

Basically if anyone has picked it up already, is this game worth buying?

Oh and discuss the game too, bit surprised there isn't a thread for it already.
