I'm going to be hated here, not trying to be a troll, but Steam IS drm.
But I'm assuming that the Apple Emulation versions of the original 3 games you get bundled with Bard's Tale are DRM free though, right?
I don't know. I guess it is possible to run them through and Apple emulator, making them DRM free. I do not have one, so I do not know. If you want to run them 'out of the box', you do so by launching the main game and selecting them from a menu there, and it needs steam running to do so.
