Doom resurrection .. not because it is better than doom classic, but specifically for this case, I prefer to look forward instead of the other way around .. why? because I was hoping ID software will release a game with doom classic gameplay with doom resurrection graphic ..
Yay! Let's compare two games with two very different types of gameplay! Yay! You've got mail! Yay! (if anyone gets the in-joke, give yourself a pat on the back )
Depends if you're a player of this gen, or the previous gen. Regardless of this I'd say both are stunning games, but I 'd have to go with Doom Classic- It just has that extra layer of polish that D:RE is missing. (Yes I'm talking about multiplayer and freedom to move) Most people are obviously going to choose RE for the graphics. I personally enjoy the classic graphics, simply because they look much, much more crisp and sharper than the majority of 3D games on iPhone.
