There is no good DRM, period. Most of it is a scam perpetrated by shady programmers that can't handle making real, useful software (cough securom cough).
The pirates are not the market, stop spending money and development time on them. Focus on giving the best possible experience to customers who buy the program. Why doesn't every damn game come with a t-shirt?
Remember code wheels? Or manual pages? Back when games came with well bound, good paper, functional manuals and not the out of date crap (or worse just a PDF) that modern games seem to contain. How about cloth maps? Anyone over 20 here remember those?
For an example of what a game package should be:
Cloth map, coin, good looking manual, supplemental story material (also a clue to an adventure in game), reference charts, coin.
If all a publisher is offering for $50 is the bits on a disk then they have an inferior product to the pirates. If they were offering all of this stuff then a gamer would have motivation to buy instead.
