For the most part, the digital versions will use whatever the digital companies use. For example, the Steam version uses Steam for its DRM. Off hand, I do not know what the other companies will use.
Crushbug, or anyone else... can you sell me on dragon's age? Here's my dilemma: I *loved* the old school might and magic games. I actually replayed 4, 5, 6, and 7 this past year. I loved the original Lands of Lore. I also loved Morrowind and thought it was a better RPG than Oblivion - just not as polished.
That said, I could not get into Neverwinter Nights. I didn't like the perspective, pace, speed... something. It just wasn't for me. Also, despite many of the good things said about the Witcher, I'm afraid to try it because I've read enough about it to make me pause.
All this said, based on what I liked - is this game going to be for me?
