The original DOOM formula, get from point A to point B and kill everything along the way in FPS was ground breaking when the game released. It started a new genre. But, I think most gamers today look for a more cinematic experience when it comes to the single player campaign. If all this is, is run and gun, it's going to be a multiplayer game and little more. I think it could still sell well as that because there are a lot of people who just multiplay, but players like myself who are not so into that and like a story may not find this one very interesting. I loved DOOM 3 because it had a good story, had scares, and good graphics. Big open maps, lots of mobs to kill, and gory kill animations are fun for a bit, but I think I would get bored fast on what I've seen thus far. Amazing graphics though.
