$200K is his living cost for 3 years? Some people don't make this amount of money in 10 years(after taxes).
I think some stuff was lost in the ellipses from what I quoted, perhaps -- pretty sure his expenses were more than living cost, as he hired an artist (actually more than one, as edmund did the animations) and some additional programming help at the end and the dev kits and translation and qa aren't free afaik. The 'just cost of living' dev would not have an artist (at least not one paid upfront ...) and would probably have to get someone else to cover the XBLA overhead (or just release on PC first instead).
