Some good points 
Aphrodite ....
I think being good at individual aspects of gamedev is completely different from actually producing an entire game. Producing and overseeing a game is more like being a record producer, or film producer job. You have to have the ability to see outside the game and/or see it from a distance. This is huge problem for indies, since usually they are a one-person shop and working very close to the nitty gritty details on a daily basis... but as we've seen it's also very possible.
I think indies, need to take their time and don't expect overnight success. Also, if you are panicking about money and selling the game you are working on, then that is a huge risk. You might consider some help if that is the case. Working with others helps focus and the other person can act as a sounding board which can help decision making.
But obviously a 1-person game will not be as "polished" or "deep" as a giant studio. But still, who's to say that a solo artist can't perform an amazing solo version of "Over The Rainbow" just as well as triple scale orchestra players can perform a Mozart symphony? It's all in the scope, and scale...
I say, make great art (games) with what you can do... once you start reaching beyond what you can do is when you fail.
