Was it the best? No. Could it have had some tweaks in mechanics, yes. But it was good, fun, and its story satisfied me in a way I hadn't been in a while. Plus it had Elizabeth. As for the more liniear nature of the game, it kinda makes sense for Brooker to not explore AS much as other characters in the Shock series, since he is suppose to be there just for Elizabeth. In the other Shock games, the character isn't motivated like Booker is, and the place they are in has already completely destabilized. Booker sees the results of his actions occurring and wants out before it gets any worse. The other characters see the aftermath of what went down, and have some level of detatchment from it.
