One could maybe receive something nifty even with online bought games... Say a little card or a small gift. But it would of course be country restricted as shipping costs a lot.

And for each card/thingy you receive, you receive points which you can redeem online.

There are lots of possibilities, and you never know until you actually do the research. Which is I think jumping directly to something like DRM is bad. They should really try to reward honest buyers, rather than punishing them.

DRM is just the most easy to use and most cost effective I guess... I mean no necessary market research there, and no need to change plans too much.
