Doom 2016 was actually pretty good. Really good in fact. What I think is that new one won't be as good. I don't know why, but highly thematic installations are so cool. System Shock 2 for its Von Braun and Rickenbacker spaceships, Dead Space 1 and 2 for Ishimura and Titan Station, Alien:Isolation for Sevastopol Station, Doom for Mars base, only super rare exception was Deus Ex. It was set on Earth, but they kept the level of fiction and immersion to such a high level it didn't bother me. Oh and Half-Life 1. Black Mesa base will be one of best experiences I've had in gaming. Still on Earth, but they executed it so well it's amazing. And I miss this. Usually it all ends up just being "some levels" on Earth, everything is too familiar. Just smearing some gore on it and make all destroyed just isn't "it". Rage did that really well with that infested hospital segment, but that was just a part of a game and it was great. But looking at entire game like that, I don't know...
So, for me it's a mixed expectation. I liked Doom 2016, but I'm not sure I'm gonna like the setup the game will be happening in...
