Smelly have you played the Killzone 2 demo yet? - ok, it is still just an FPS - but its not just "same old same old", the graphics are stunning, not just pretty but the animations are something special. The game "FEELS" alot better than most shooters, your not playing as a floating gun, you can feel the weight behind your movements. And the AI is amazing - played through the demo a couple of times trying different tactics to see if different things would happen and the enemys react completely different, not many other games pull that off right.
Ketchup - Bioshock was indeed an amazing game, loved the moral choices it gave you, and the setting is lovely, although I only rented it and managed to get all I would be able to out of the game in one week. Saying that if I saw it for 2 quid I'd definitely pick it up!!!!
