Technically speaking you're right, but practically the scene isn't anymore designed for this kind of approach.
This thread wouldn't have existed if the scene weren't saturated by average games. And the fact that, like
Crimson Delight Games said, those games are generally better than what we got in the past alas don't help. In the end, your first game will generally pass unnoticed, burning all your budget and hopes.
Of course, you'll become an established author and you'll have one finished game in your portfolio. This can help for the future, but what future do you have when you don't have anymore money to put on a game, and lost the most part of your passion releasing a game that no one played ?
It's the paradox of the scene nowadays. If you want a chance to standout and one day be successful enough to not lost money, you need to do something different and more ambitious. Or you need to pass more time advertising for your game than effectively working on it. But the last option is a trap, because once successful you'll want to finally works seriously on your game, what will mean more time between two releases and you'll be accused to milk your patrons...
And after starts threads to complain about the lack of creativity and quality in the scene...
