I don't have the free time to commit to creating my own stuff in Project Spark, but I'm really excited to see what some other people come up with.
I think the reason the game isn't getting as much love as it deserves is simply because the X1 launch line-up is so stacked. We already have Ryse, KI, Forza, Quantum Break, COD: Ghosts, BF4, Titanfall on the horizon, whatever Kinect has in store, etc.
