I don't know if a new DOOM is required or not. It seems that type of gameplay style has long since died out. Not saying that is a good thing. I really f*cking miss oldschool shooters where you could move super fast, be dead accurate without having to slow down and use iron sights and just lay waste to sh*t with ease. As well as non regen health.
I never played DOOM 3, I don't know if people enjoyed that or not or even saw it as good as a true 3rd game.
All I know is either take the time to get it right and make it a true DOOM experience with the right atmosphere, music and gameplay. I love the old smooth style of 1 and 2 and duke nukem. I don't think that can be accurately replicated in a fully 3d game with a modern realistic game engine.
But what the f*ck do I know.
I just hope they take their time with it and it doesn't suck weiners.
