If you like the 2 previous games then you'll like this. I'm even finding the story to be more enjoyable than the games predecessors.
But the maps just too big, and it has a habit of sending you from 1 side of It to another consistently.
I wouldn't say It's as polished as the other 2 games either, I've found a few glitches and have had It freeze on me a few times. Geniuely get the impression that the games been rushed out to beat the wave of next gen consoles.
