I see so many startup companys, esp. in Silicon Valley - who nothing about getting product shipped. Case studies in how to waste VC bucks and go broke and have squat to show for it.
HT went off, built a better mousetrap, and keeps the overhead low (I think) and the company moving ahead. No grand ambition of porting the code to a space game, and a WWI game, and everything under the sun - just one game - his game - and done right.
Think about how rare that is these days.
