Yes, I agree. While reading a Dark Arena review a while back I noticed that they said the game had OK graphics, OK sound... OK everything, but in difference to Doom is was just plain boring. So I watched some gameplay and you walk... turn... shoot... shoot... enemy dies, then you keep walking. And I started thinking about what makes this different from Doom and it's definitely the pace.
I think Doom makes up for open, empty spaces and low fidelity gameplay by having it all happen at such a lightning speed so you still get a pretty high detail per second ratio or something such. It's hard to define why Doom and even Quake work out at such high speeds and would definitely not work at a realistic pace while modern games work at slower paces but not Doom-speed.
I think the number of enemies could have something to do with it. Modern games have so few enemies if you had Doom-superpowers everything would be dead in a minute.
Anyways playing Doom with a mouse and keyboard just gives you super-smooth controls being able to move both with the mouse and keyboard at the same time... works great.
I also agree Doom is kind of styled to go at a fast pace. You pick up everything instantly, weapons fire fast, no reloading, enemies are blown away by your shots and imps shoot fireballs that make you have to move around quickly.
Ultimately I think Doom works at such speeds is because it doesn't require a lot of precision. Most weapons spray all over the screen unless you're far away from your enemy. Crysis 2 multiplayer is pretty fast but it also requires a lot of precision because the maps are huge, the enemies are tiny and this doesn't work as well as Doom. In Crysis 2 hitting a small, lightning fast target is pretty difficult while in Doom you've got smaller maps, bigger hitboxes etc.
