Just watched the videos.
Liked:
Id Tech 6 doesn't look spectacular but it performs well and the environment looked fairly good (inb4 it turns out that textures look worse than Quake 3's on closer inspection).
There are some nice lightning effects and explosions and particle effects looked good enough to me. Too bad there is little to no environmental destruction.
The inclusion of a
level editor is always a good thing.
Disliked:
PC could look up and down, where are mah sprites.
Slow player movement.
Most enemies, weapons and the environment don't feel like Doom at all, these people made a more action-packed sequel to Doom 3 instead of a reboot of the original game(s). They didn't capture any of the original games' atmosphere or intricacies. Also what happened to the colours, Doom 4 looks as bland and generic as they come.
Cheap Gore galore, I like my first-person shooters bloody but id dialed up the violence to 11 in the hope of pleasing the Brûtal "Doom" crowd. Most of the gore looks poor, the enemies don't gib properly they just fall apart in a unconvincing manner, remains disappear instantly.
Enemies glow when they're ready to be executed by the player
The weapon wheel and accompanying slow-down effect (probably non-issues on PC but still) and the canned animations (climbing, landing,...) and those moronic executions all break the flow of the gameplay which is the last thing you want in a proper FPS...
Very linear, mostly claustrophobic level design (similar to RAGE and TNO) interspersed with smallish arena fights, no room to circle-strafe and speed-strafe...but there's no real need to dance with demons anyway because they're all push-overs that only exist to give the player an easily achievable power fantasy, they pose no real threat whatsoever. (Maybe the final game will be more challenging but this is how they decided to present their game...)
Borderlands style item drops with annoying sound effect.
On-screen flashing Idiot Messages like “low health” right next to your health indicator...
