… there is probably some benefit.

I was not thinking about the business side but rather about what the customer gets out of it. What bothers me about DRM systems is that they cause problems that you don't have with pirated game, which is the opposite of how it should be. I don't want to struggle to get a game running, when the pirated version does not caus those problems. That being said, I haven't bought any large AAA title in years and my experience is from 7+ years ago. Maybe things have changed but I kinda doubt it.
