I love this game. Its easily one of the better titles of its year. Stories great, graphics amazing, frame rate now fixed via the update, water effects god damned incredible, and the gameplay dynamic and intense.
I love how your rewarded for smart play. My first run through wasn't too good. Mostly run and gun with offensive powers, and the enemies got too hard to kill. The second time through, I researched the enemies with the camera and actually spent the ADAM on tonics instead of powers. It was so much more fun when you know when your doing.
Easily the most useful Plasmid is Enrage, and its also the first available, and the cheapest. It was so fun to hit a passing bad guy with it, and watch him charge a Big Daddy with a pipe, then see him get smacked against a wall or onto a table. The physics are top notch too.
Anyone else play this? I know its a single player campaign, but I think theres enough reason to play it a few times.
