Best Doom game of them all. Doom Eternal is nowhere near as good, not even close. I wonder how new Doom The Dark Ages will go, but it already looks better than Eternal because it has no stupid forced mechanics...
Seem like Doom want eternal wanted people to be switching weapons constantly like high-level players of Doom 2016. But it just wasn't as fun to do it that way for every player
For me the forced mechanics of glory kills, chainsaw and flamethrower put me off in Eternal. Instead of managing ammo by collecting it and smart use you were forced to do above mechanics and they felt, well, super forced and stupid.
Doom 2016 gave you option, collect normal way or use chainsaw. I never used chainsaw through entire game for it and always had enough ammo. I played it on Nightmare iirc.
From what I was told by Digital Foundry when they previewed game's engine, they mentioned The Dark Ages doesn't have any of these forced mechanics which is cool.
I've played both 2016 and Eternal and finished both on Ultra Nightmare on both controller and KBM.
2016 was more of an artificial difficulty bump with enemies killing you very quickly and lots of restarting.
Eternal was more of a skill check. If you died it was because you weren't good enough with the mechanics of the game. You should have been faster and been better with decision making.
It took me a long time to realize that dying and respawning with extra lives was part of the main game loop. In most other games, dying is to be avoided.
Once I realized that, the game was honestly too easy.
I personally enjoyed both, but I understand why people wouldn't like Eternal. It's more of an action game than a shooter like 2016. The gameplay is still fast frantic and fun in my eyes. Only a handful of games actually have the same fluid first person movement that Eternal has. Titanfall 2 is one of them.
Gamers keep complaining about easy mode in games but also complain that Eternal is too hard with the ammo and shield management. Just can't satisfy everyone really.
