Ah yes, the "Collector's Edition" of a fourth copy-and-paste game. That may ring true, but there continue to be incremental additions that do set it apart: dynamic backgrounds, a new objective that interacts with them, and some pretty good music tracks. The story is a bit dodgy this time, but this is certainly another pack of levels for the series. I just wish the de facto difficulty levels still weren't "on autopilot" and "play perfectly".
