I like how they discussed dropping over the ledge in the garden area to get to the helipad and gave up, but never investigated the part of the ledge on the left hand side where you can totally do that.
It makes sense not to include the camera because it keeps the price at $399 and they probably consider a large number of PS4 users already have the camera. The camera SKU already exists in the supply chain, from a cost perspective it's a smart play because they don't have to make a (more expensive) deluxe PS-VR SKU, and they can boast the $399 price (even if it is not 100% honest).
Flower was definitely a good use of Sixaxis controls. I agree, most games using sixaxis felt forced but I like how natural flying around felt in Flower.
