But I'd love to be proven wrong.
You could also pick up a CAVE game, but it would be by no means indie...
On the PC front I am familiar with more options, but it really depends on what you like. I play mostly shmups, puzzle games, and platformers, which happen to be really easy genres to make indie games in. Over the last few years I've enjoyed Jamestown, Thomas Was Alone, Electronic Super Joy, Antichamber, Super Hexagon, and a lot of games that are distributed for free in places like http://www21.atwiki.jp/iwannabethewiki/pages/283.html
If you're a business person, games are probably a poor investment. If you're an independent creator, it's still one of the most self-sustainable forms of art.
This is like saying, "If anyone was making great music it would be at the top of the Billboard charts and I'd hear it on the radio on the way to work." or "If anyone was writing good books, they'd be outselling Dan Brown and I'd see it in the supermarket isle, so I guess nobody is."
If you are into music you can find great music. Same with games. But you will have to do at least a little looking.
