I don't want a 20 years old game with better graphics. I want a new game that'll show me one of my favourite franchises 20 years later. I want an interesting plot presentation (even though it's still the simple "demons attack, kill them" type of thing). I want cool scripted sequences and mind-blowing cinematics from time to time. Why not? I've been playing pure run&gun oldschool DOOM for 20 years. I don't care how "oldschool" or "hardcoe" DOOM 4 is as long as I have fun and feel good about it.
I try not to envision the game itself too much to avoid making up expectations. But I'll say a couple of things.
* Action core is obviously one of the priorities for a DOOM game. I think RAGE was a big step in a right direction there. The feel of movement, weapons, effects and enemy responses were all handled remarkably well. As long as id continues working along those lines we should be fine. Just don't spam invisible walls all over the place again.
* One of my personal requests would be to try to create a bit more open environments. BioShock 1/2 did it very well. Levels are linear in terms of critical path but there's a lot of:
- interconnectivity which makes the levels more believable, more interesting in the gameplay space and extends the in-game illusion of freedom
- semi-non-linearity allowing playing areas in a different order
- a good amount of optional, exloratory spaces
* Continuing from the previous point, DOOM is a game about action and exploration. Even if the levels do end up being more linear like DOOM 3 / RAGE, there should still be a bunch of optional places.
* There's a lot of opposition towards anything that might detract from pure run&gun gameplay. I think as long as it's (i) justified and (ii) enriches the gameplay, go for it. Obviously the "hardcoe" fans will say "no! guns, explosions, blood and guts all over the place is what DOOM is about, nothing else!" but, like I said, such opinions don't really matter to me.
