He did succeed, only he didn't define success very well. 1. His game got good reviews and did quite well. 2. He set a target at 700 units. He should've set the target at x units / month.

I sometimes get nervous with ~1.5 years of savings and I'm not aspiring to start on my own. Seems like he was a little bit naive in the financials.
