Just booked it. Last years conference in Seattle was beyond anything I could've imagined. The experience was hugely informative in a number of ways, and provided a huge confidence boost when real-life professional developers all lit-up every time I pitched "Car Jumper" to them. Unfortunately, George and I really had no clue what we were doing, but because we'd shipped "Car Jumper" to OUYA, we thought we'd give the conference a whirl. Unfortunately, all we had to show was a grainy Youtube video (that didn't always load, especially when talking to a publisher).
I'm setting a goal right now: 3 prototypes, on my phone, by the end of summer. Specifically, by my birthday at the end of August. "Car Jumper" first, followed by that shooter prototype, then, if there's time, a third thing that I've been dying to explore. Should be an interesting couple of months...
