One of the things that I really didn't like about DD was the original hard mode. It literally did nothing to the game, enemies just do more damage to you and that's it =/. It basically killed the replay value for me. I'm also annoyed that DA can't just be normally downloaded and that I have to buy the whole game again which is just an added cost. Yeah they sort of made up for it, but unlimited port crystals really isn't enough for me. But in the end I'll be buying DA.
