HOLY FRAKKING PARTS PACK!
I ordered the new LEGO Chess set just for parts. After all, it is only $55 for 1450pcs. I looked over the parts inventory on Brickset before ordering, but they don't list all the parts.
They don't show that it comes with 8 dark grey 16x16 plates. And they certainly don't show that it has 12 each of 1x10 and 1x12 grey bricks.
But the real gem is that it has 96 of the brand new corner SNOT bricks in tan.
The only newish parts it is missing in bulk are the 1x2x5/6ths SNOT bricks like Brick Bank had, and those 1x1 pyramid pieces introduced in Nexo Knights.
If you are into MOCing and salivate at handy new parts each year, this thing is a gold mine for the price. I was happy just having bulk in some things from this, but having nearly 100 of those new corner SNOT pieces in one relatively cheap set makes this a fantastic purchase.
EDIT: And oh, all that bulk of white and black 2x4 bow pieces. I knew that going in, but it is glorious to get so much at once.
