Regarding the top 25 meaningful revenue... this all depends on your team size, does it not? If you are solo or a team of 2-3, you need a lot less revenue than a big company.
We're almost done with our slot machine game for iOS (lame, I know), but we only have 2 people, and we definitely don't need to be in the top 25 to make some real money (that can fund new, "real game" projects).
Do some reading to figure out what kinds of returns you can expect. I've seen 1 and 2 person teams basically able to replicate a medium income job. That's great if you can make it sustainable, but I don't think anyone's getting rich outside of the glamorous world of a few big indie titles.
