Well not blogged for ages so time for an update.
I finished Bioshock a few weeks back, in the end despite the difficultly spike (more on that later) I thoroughly enjoyed the game. I found it to be a totally absorbing experience, the environment, the pacing, the audio, the whole design was head and shoulders above most FPSs
So that difficultly spike, well in hindsight I should have just wandered past the particular Big Daddy, got myself tooled up and tackled him when I was stronger. So in fact the real issue was not a difficult spike but rather the game never told you a few key facts. Firstly you don’t have to fight them, they wander the levels so you can fight them at anytime (or not), secondly Big Daddies totally ignore you unless you attack them. In fact the game tries to tell you the exact opposite, with the first Big Daddy encounter being mandatory and Atlas informing you you’ll have to kill them in order to survive.
Still looking back on it Bioshock was an amazing game, and I’m really looking forward to the sequel.

thank you
