A game that's crappy and nobody cares about is "unpiratable". I'm sure game companies would love to have other forms of "unpiratable" games, but "if there's a will, there's a way" is an old axiom that hasn't been disproved thus far.
The way I see it, companies are wasting precious resources to develop new DRM that they could use to make games more fun to play, and give people more incentive to buy them. The way it is now, you get games that you don't know are good or not, because they're unrentable, don't have demos, and are impractical to buy-and-resell, because of restrictive DRM. And I really can't see how this would benefit the sales.
