My kids love Mega Rigs, and rightly so - they are awesome. This year's set appears to be all new. They tend to re-use molds a lot, but I can't recognize any parts here.
Mega Rigs are modular vehicle sets with figures. You can mix and match parts from different sets, and each has a stunning amount of detail on them. Truely one of the most underlooked toy lines in recent memory. Very kid focused, but if you were a kid, you'd want these.
