To be honest, I haven't played it, but watching the reviews and previews for it, whether they were successful or not, their ideas were exactly the kinds of things I wish other games would improve upon. They were also the particular things I thought were highly lacking in the first game, which I did play.
I'm also guilty here. I tried replaying it and didn't get very far in before I quit. The gameplay is standard shooter, and there's not a lot of replay value. More variety in skills, and more usefulness would've added a lot. A better variety of enemies would've been great too.
Bioshock-type story + Fallout 3 type gameplay + a better shooter = Awesome
