As for the market, I wouldn't really know. It seems more and more indie games are running around, and at the same time, non-indie games are still heavy on the market. While it's true that there's less need for publishers now than before, they're still handy and still being used.
But as far as the games themselves go...
While to me, a game is just a game, whether under a publisher or not (aka indie).
However, there are some fine differences. For example, most indie games really show some neat new things never seen in most games, if ever done at all. Though, this could be a good or bad thing. Because some put a lot of effort into a bad idea, but hey, it's not like they have some bigshot publisher expecting the greatest moneymaker alive. They can make these mistakes. While non-indie games seem to expand and develop things we're already familiar with, they do it much better. Rather than a group of 5 people, they have a company working on improving every piece of the game. I can enjoy both sides and really, as long as someone makes a fun game, I'll buy it.
