No kidding. I just recently played through Doom 1&2 and think Doom 2016 fits in nicely so far from what I've seen.
The new Doom seems to have a lot in common with Doom 1&2:
- Huge labyrinth like levels
- Great enemy design
- Great graphics
- Kick Ass Soundtrack
- Circle Strafing
Now I can't discern from what I've seen if the game's guns feel as good as they did in the original. I've yet to play a game since Doom that has really done a better Shotgun. But for those that say "this isn't Doom", they should articulate as to why as I just don't understand the complaints and feel many aren't validating why "this isn't Doom."
It mixes some modern design trends with older design sensibilities and that may upset some people, which is understandable to a degree I guess if you only want a strict visual upgrade to Doom. But at that point, just play Doom 1&2 with the billions of mods that upgrade just about every aspect of the game if you want.
Don't like load outs? Don't play the modes that use them. Want to ADS? Go play CoD/BF*/Every other shooter released.
