Got this a few days early and have been really enjoying it! I'm about half way through and so far it's my fav of the TFB-made games. A little surprised by the IGN review, but the prominently placed prompt for in-game microtransaction IS gross -- an adult will see how pointless they are, but kids are kids -- and they deserve to take some flak for that.
The campaign is a few levels shorter than usual -- 10, plus the 2 smaller bonus elemental levels accessible with the various starter pack characters -- but there's a lot of additional gameplay content spread out over the new overworld area. If there's a little more similar side stuff introduced post-game stuff then I'd say it balances out to about the length of Superchargers, just presented in a more compartmentalized way. (I'm not done the campaign yet, though, so I can't speak to that.)
Side note: because of how the game has been restructured, there's a much bigger content discrepancy between the regular starter pack and deluxe (Crash) starter pack than usual. In addition to the Crash stage itself, you can also use Crash and Cortex to open up two more of the bonus elemental levels... so, that's one BIG level and two smaller ones that you can't play with the regular starter.
