I finally went ahead and bought the game! Love it! The story and setting are absolutely fascinating. As great as Rapture was, I think this is even more interesting with the dimensional tear mystery. And I love having Elizabeth with me.
One thing is driving me up a wall. The save system. I can't save the game it only auto saves. I play to the end of a chapter where I load a new location, then make sure it auto saved and turn off the game. TWICE now I have had to replay AN ENTIRE HOUR of the game because when I turn the game back on it doesn't remember I finished that damn level!!! Did anyone else have this problem?!
